OPINION
Opinion by
This is an insurance coverage dispute where we interpret the duty to defend in commercial general liability (CGL) policies. The trial court decided cross-motions for *375 summary judgment in favor of Federal Insurance Company and against Samsung Electronics America, Inc., Samsung Telecommunications America, L.P. f/k/a Samsung Telecommunications America, Inc., and Samsung Electronics Co., Ltd. (Samsung) on Federal’s duty to defend and indemnify Samsung in five underlying class actions. 1 Samsung contends the trial court erred by rendering judgment for Federal because Federal has a duty to dеfend Samsung in the class actions. We affirm in part, reverse and render in part, and reverse and remand in part.
BACKGROUND
Samsung is a manufacturer of wireless handheld telephones (cell phones). It was named as one of many defendants in the Pinney and Dahlgren complaints seeking damages allegedly arising from the use of its cell phones. 2 Although the complaints were filed in different forums and contained variations in the wording of their allegations, all alleged that defendants’ cell phones emit harmful radio frequency radiation that potentially causes injury to human cells whеn the cell phones are used without a headset. Samsung tendered the defense of the complaints to Federal, from whom it had purchased CGL and excess umbrella liability insurance policies, because it believed the class actions alleged “bodily injury” and sought “damages because of bodily injury” under Federal’s policies. 3 Federal defended Samsung in the Pinney class actions under a reservation of rights but declined to defend Samsung in the Dahlgren class action because the plaintiffs in that action expressly disclaimed damages for personal injury resulting from the use of the cell рhones. Federal also sought a declaratory judgment that its policies did not obligate it to defend or indemnify Samsung in any of the class actions.
Federal and Samsung filed cross motions for summary judgment on Federal’s duty to defend and indemnify Samsung. Additionally, Federal sought reimbursement of the defense costs it had already paid in defending Samsung under the reservation of rights. Without stating the grounds, the trial court granted Federal’s motion for summary judgment in part, holding Federal had no duty to defend or indemnify Samsung in the class actions. The trial court also granted Samsung’s motion in part, holding Federal was not *376 entitled to reimbursement of past defense costs. Samsung appeals the judgment.
STANDARD OF REVIEW
We review a grant of summary-judgment de novo.
Gehan Homes, Ltd. v. Employers Mut. Cas. Co.,
When the trial cоurt does not specify the basis for its ruling, it is appellant’s burden on appeal to show that each of the independent grounds asserted in support of summary judgment is insufficient to support the judgment.

Applicable Law
The insurer’s duty to defend arises when a third party sues the insured on allegations that, if taken as true, potentially state a claim within the terms of the policy.

Discussion
A. Do Allegations of “Biological Injury” Potentially State a Claim for “Bodily Injury” under Federal’s Policies?
The parties have not cited and we have not found any Texas case that interprets the term “bodily injury” in a CGL policy to include or exclude alleged injury to human cells. In determining this issue of first impression, we look first to the language of the policies. Federal’s policies provide:
We will pay damages ... because of:
bodily injury ... caused by an occurrence ...
to which this insurance applies.
This insurance applies ... to bodily injury ... whiсh occurs during the policy period ...
[[Image here]]
Bodily injury means bodily injury, sickness, disease or, if arising out of the foregoing, mental anguish or mental injury sustained by any person which occurs during the policy period, including death at any time resulting therefrom.
[[Image here]]
Occurrence means an event, including continuous or repeated exposure to conditions which results in bodily injury....
1. Samsung’s Contentions
Samsung contends the complaints alleged a claim potentially covered by Federal’s policies because they alleged plaintiffs suffered an “adverse cellular reaction” or “cellulаr dysfunction,” also referred to as “biological injury,” when they used Samsung’s cell phones without a headset. Samsung contends these allegations were sufficient to allege “bodily injury” within the meaning of Federal’s policies. To support its argument, Samsung primarily relies on decisions of three other jurisdictions interpreting these same class action allegations as well as a line of asbestos cases.
Samsung argues that three of the four other jurisdictions that have considered these precise issues found that cellular level injuries constitute “bodily injury” for рurposes of the insurer’s duty to defend.

In
Northern Insurance Co. of New York v. Baltimore Business Communications, Inc.,
Samsung also analogizes the "injury alleged in the underlying complaints to the injuries alleged in asbestos cases. Samsung relies on the Fifth Circuit’s opinion in
Guaranty National Insurance Co. v. Azrock Industries, Inc.,
2. Federal’s Contentions
Federal argues the class actions did not allege “bodily injury” becausе they alleged only risks to health associated with radiation exposure and did not allege any plaintiff suffered a diagnosable disease or discernible sickness from the exposure. Federal argues that “bodily injury” requires a “practical loss of functionality, not a mere ‘cellular effect’ [that resulted] in no detectable impairment, illness or disease.” Absent discernible physical injury to the body, Federal argues there can be no “bodily injury” under its policies.
Federal also contends the class actions did not allege “bodily injury” because thе class actions seek only economic damages measured by the cost of headsets; the class actions avoided pleading “bodily injury” because allegations of individualized injury would defeat certification as a class; membership in the class was predicated, not on harm, but on whether the person had purchased a cell phone without a headset and included both past and future purchasers of cell phones; and purchasers who had been diagnosed with a brain tumor or cancer of the eye were excludеd from the class.
To support its argument, Federal primarily relies on
Trinity Universal Insurance Co. v. Cowan,
Federal alsо cites several cases that addressed whether derivative claims for mental anguish and loss of consortium are “bodily injury” for purposes of the respective liability policies, but we do not find those cases helpful to our analysis because they concerned statutes and issues not relevant here.
See, e.g., McGovern v. Williams,
3. Analysis
Federal’s policies define “bodily injury” as “bodily injury, sickness, disease” that occurs during the policy period. Although the policies do not further define “bodily” or “injury,” the
Cowan
court concluded that the term “bodily” implied a physical rather than mental injury and required “an injury to the physical structure of the human body.”
Cowan,
Notably, jurisdictions that have interpreted these same or similar policy provisions have concluded “bodily injury” includes injury at the cellular level.
See Baltimore Business,
Federal has presented no persuasive argument why injury to human cells should not constitute “bodily injury” under its CGL policies. And to adopt Federal’s narrow construction that the injury must be diagnosable, identifiable, or a discernible physical injury to the body would require us to read language into the policy that is not there.

B. Do the Complaints Allege “Bodily Injury” and “Damages Becausе of Bodily Injury”?
We now turn to the question whether the Pinney and Dahlgren complaints alleged “bodily injury” and “damages because of bodily injury” under Federal’s policies.
1. The Pinney Complaints
In their amended complaints, the Pin-ney class plaintiffs alleged:
Defendants knew or should have known that their [cell phones] emit radio frequency radiation (RFR) from the antenna that causes an adverse cellular reaction and/or cellular dysfunction (“biological injury”) through its adverse health effect on: calcium ion distribution across the cell membrane, melatonin production, neurological function, DNA (single and double strand breaks and chromosome damage), enzyme activities, cell stress and gene transcription, and the permeability of the blood brain barrier (collectively hereinafter sometimes described as “the health risk” and/or “the biological effects”).
[[Image here]]
Each time a [cell phone] user makes or receives a call, a wireless signal is transmitted from the [cell phone] antenna to the nearest cell tower or from the nearest cell tower to the [cell phone] antenna, respectively, thereby exposing the [cell phone] user to RFR.
[[Image here]]
Each time plaintiff used the [cell phone] in the customary position, the antenna was located next to plaintiff[’]s head.
[[Image here]]
Each time plaintiff used the [cell phone], he was exposed to RFR which emanated from the antenna, thereby subjecting plaintiff to RFR and, in the absence of a headset, to RFR[’]s biological effects and the risks to human health arising therefrom.
*381 [[Image here]]
At all relevant times Defendants knew or should have known that Class Plaintiffs are exposed to RFR while using a [cell phone] and as a result are at increased risk for biological injury.
The Pinney complaints also alleged Samsung knew plaintiffs incurred “biological dаmage and/or harm” from using its cell phones. The allegations explained that this “biological injury” included adverse health effects on, among other things, the cell membrane, melatonin production, and neurological function. The class plaintiffs detailed the research studies which showed that exposure to radiation produced changes in genetic material, a precursor to cancer, and resulted in changes in brain activity, reaction times, and sleep patterns.
The Pinney complaints alleged both present and future injuries. They alleged present “biological injury” each time plaintiffs used their cell phones without a headset. They also alleged the potential for future serious health problems. Federal argues the allegation in the Pin-ney complaints that “no individual issues of injury exist” means the Pinney plaintiffs expressly excluded any claim for “bodily injury” within the meaning of Federal’s policies. We disagree. Instead, we interpret that phrase to mean the Pinney class plaintiffs have not alleged the manifestation of an injury, sickness, or disease presently, but have alleged their bodily cells were adversely affected from the exposure tо radiation emitted by the cell phones.
An insurer’s duty to defend is based on its policy provisions and the allegations in the pleadings.
See Gehan,
Next, Samsung argues the Pinney complaints sought “damages because of bodily injury” obligating Federal to defend Samsung because they sought “compensatory damаges including but not limited to amounts necessary to purchase a [cell phone] headset” for each class member. Samsung argues the relief sought — a cell phone headset — -is clearly because of alleged exposure to radiation and constitutes “damages because of bodily injury.” Federal argues the costs of cell phone headsets are economic losses and not a result of “bodily injury.”
We look first to the definitions in Federal’s policies, which provide:
Damages because of bodily injury include damages claimеd by any person or organization for care, loss of services or death resulting at any time from the bodily injury.
The policies do not further define “damages,” “because of,” or “care.” The parties have not cited and we have not found any Texas case that interprets these phrases, so we give the terms their plain, ordinary meaning.
See DeWitt County Elec. Co-op., Inc. v. Parks,
As we did in determining the definition of “bodily injury,” we also look to other jurisdictions that have considered these allegations and similar insurance provisions. In
Voicestream Wireless Corp.,
the Ninth Circuit held that the class actions sought “damages because of bodily injury” because the plaintiffs sought maximum legal and equitable relief and punitive damages, and the cost of a headset neither clearly fell within the policy оr was clearly excluded by it.
Voicestream Wireless Corp.,
The recent case of
Ericsson, Inc. v. St. Paul Fire and Marine Insurance Co.,
We agree with the reasoning in these cases. The Pinney complaints alleged that exposure to radio frequency radiation from the use of cell phones without a headset caused an “adverse cellular reaction” or “cellular dysfunction” that caused “biological injury” and could result in serious health conditions in the future. The damages sought by the complaints — a cell phone headset for each class member who had purchased or leased a cell phone without one — are sought “on account of’ or “by reason of’ the plaintiffs’ exposure to radiation from the cell phones. And the cost of *383 a headset is not clearly within or excluded by the definition of “damages” in Federal’s policies. Accordingly, we conclude the damages sought potentially state a claim for “damages because of bodily injury” triggering Federal’s duty to defend the Pinney complaints.
2. The Dahlgren Complaint
The Dahlgren complaint asserted claims for false and misleading representations regarding the potential risks associated with the use of Samsung’s cell phones and for unjust enrichment. It claimed that as a result of Samsung’s conduct, the Dahlgren plaintiffs were injured by paying for cell phones that did not comport with the description provided by Samsung. The Dahlgren complaint expressly disclaimed damages for personal injury:
This action does not assert personal injury claims, such as claims related to the harmful physical effects that result from any class member’s use of [cell phones] ... Plaintiff and the Class seek economic and related equitable relief.
The Dahlgren complaint sought statutory damages, punitive damages, attorney’s fees, an injunction, and the imposition of a constructive trust for Samsung’s allegedly ill-gained profits from which class рlaintiffs might seek a refund of the purchase price of their cell phones.
But unlike the allegations in the Pinney complaints, the allegations in the Dahlgren complaint did not allege “bodily injury” within the meaning of Federal’s policies, and, in fact, expressly excluded any such claim. Additionally, the alleged damages derived solely from Samsung’s misrepresentations and not from a “bodily injury” covered by Federal’s policies. Accordingly, we conclude the Dahlgren complaint did not assert facts which, if true, would provide coverage under this portion of Federal’s policies. As a result, Federal did not have a duty to defend Samsung in the Dahlgren class action. We conclude the trial court did not err by granting summary judgment in favor of Federal with respect to the Dahlgren complaint and we affirm the trial court’s judgment in part as it relates to Dahlgren. 6
C. Does an Exclusion Apply?
Federal argues that even if the class actions alleged “bodily injury” and sought “damages because of bodily injury,” it nevertheless is under no duty to defend Samsung because several “business risk” exclusions applied to preclude coverage. We disagree. The exclusions upon which Federal bases its argument are exclusions for “property damage to your product,” “property damage to impaired property,” 7 and damages for the recall of the product. The class actions did not contain allegations of property damage to the cell phones, damage to other (“impaired”) property, or the recall of the cell phones. As a result, these exclusions do not apply to preclude coverage.
Conclusion
Applying the eight corners rule, we conclude Federal owes Samsung a duty to
*384
defend in the
Pinney
complaints. We reverse the judgment of the trial court and render judgment that Federal owes Samsung a duty to defend in the
Farina, Pin-ney, Gilliam,
and
Gimpelson
class actions. As a result of our decision, we also conclude the trial court’s ruling on Federal’s duty to indemnify in the
Pinney
complaints was premature.
See Gehan Homes, Ltd.,
We further conclude the trial court correctly ruled that Federal did not owe Samsung a duty to defend in the Dahlgren class action. Accordingly, we affirm that part of the trial court’s judgment awarding summary judgment in favоr of Federal regarding the Dahlgren lawsuit.
Notes
. Four of the five complaints, Farina v. Nokia, Inc., No. 002527 (Ct. of Common Pleas, Phila. County, Apr. 19, 2001); Gilliam v. Nokia, Inc., No. 15692-2001 (N.Y. Sup.Ct., Bronx County, Apr. 23, 2001); Finney v. Nokia, Inc., No. 01-MD-1421 (Cir.Ct., Balt., Apr. 19, 2001); and Gimpelson v. Nokia, Inc., No. 2001CV38932 (Ga.Super. Ct., Fulton County, Jun. 8, 2001), which are substantially similar in all material respects, assert a combination of state law claims for strict products liability (failure to warn, design or manufacturing defect), violations of state consumer laws, breach of implied warranties, negligent misrepresentation, fraud by concealment, civil battery, and civil conspiracy. We refer to these complaints as the Pinney complaints. The fifth complaint, Dahlgren v. Audiovox Commc’ns Corp., No. 02-0007884 (D.C.Super.Ct., Sep. 6, 2002), asserts violations of state consumer laws and unjust enrichment. We refer tо this complaint as the Dahlgren complaint.
. Unlike the Pinney plaintiffs who alleged biological injury from the use of Samsung’s cell phones, the Dahlgren plaintiffs expressly disclaimed any damages for physical or biological injury arising from the use of the cell phones and alleged their injury was paying for cell phones that did not comport with the description provided by Samsung.
. Several primary and excess insurance policies are at issue in this case. For our purposes, we refer to them collectively because any variations in wording do not affect the issues on appеal.
