OPINION
Opinion by
This is the second of two insurance coverage disputes in which we interpret the duty to defend in commercial general liability policies. Appellant claims the trial court erred by granting summary judgment in favor of the insurance carrier and against the insured, a manufacturer of wireless handheld telephones (cell phones), on the insurers’ duty to defend the manufacturer in underlying class action lawsuits seeking damages for alleged biological injury from exposure to allegedly harmful radiation emitted by the manufacturer’s cell phones when used without a headset. 1
In this case, Nokia, Inc. was named as one of many defendants in the underlying lawsuits. 2 The complaints alleged that de *387 fendants’ cell phones emit harmful radio frequency radiation that potentially causes injury to human cells when the cell phones are used without a headset. Nokia tendered the defense of the complaints to its insurers, from whom it had purchased commercial general liability (CGL) and excess umbrella liability insurance policies. Zurich Insurance Company sought a declaratory judgment against Nokia, Federal Insurance Company, and National Union Fire Insurance Company that its policies did not obligate it to defend or indemnify Nokia in the underlying lawsuits. Nokia counterclaimed against Zurich and cross-claimed against Federal and National Union asserting breach of contract, breach of the duty of good faith and fair dealing, and violations of the insurance code. Zurich filed a motion for summary judgment on its duty to defend and indemnify Nokia. Nokia, Federal and National Union each filed its own motion for summary judgment on those same issues. Without stating the grounds, the trial court granted the motions of Zurich, Federal and National Union, holding the insurers had no duty to defend or indemnify Nokia in the underlying lawsuits. The court denied Nokia’s motion on those same issues. The trial court then severed these claims for purposes of appeal. We affirm in part, reverse and render in part, and reverse and remand in part.
Standard of Review
We review a grant of summary judgment de novo.
Gehan Homes, Ltd. v. Employers Mut. Cas. Co.,
When the trial court 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.
See Star-Telegram, Inc. v. Doe,
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
Our analysis of whether the insurers owe Nokia a duty to defend in the underlying lawsuits begins with the language of the insurance policies, which provides 3 :
The company will pay on behalf of the insured all sums which the insured shall become legally obligated to pay as damages because of
A. bodily injury ...
[[Image here]]
to which this insurance applies, caused by an occurrence, and the company shall have the right and duty to defend any suit against the insured seeking damages on account of such bodily injury ..., even if any of the allegations of the suit are groundless, false or fraudulent, and may make such investigation and settlement of any claim or suit as it deems expedient....

SECTION VI — DEFINITIONS
[[Image here]]
*389 3. “Bodily Injury” means bodily injury, sickness or disease sustained by a person, including death resulting from any of these at any time.
⅝ ⅜ *
9. “Occurrence” means an accident, including continuous or repeated exposure to substantially the same general harmful conditions.
1. Do Allegations of “Biological Injury” Potentially State a Claim for “Bodily Injury” Under the Policies?
Nokia contends its insurers must defend against the complaints because the complaints seek “damages because of bodily injury” by alleging that Nokia’s cell phones caused biological injury in the form of subclinical damage to plaintiffs’ cellular structures and processes. Nokia relies on
Guaranty National Insurance Co. v. Azrock Industries, Inc.,
In
Samsung Electronics America, Inc. v. Federal Insurance Co.,
No. 05-04-01316-CV,
We reasoned that to exclude biological injury to human cells from the definition of “bodily injury” would require us to read language into the policy that was not there.
Samsung,
2. Do the Underlying Complaints Allege “Bodily Injury” and “Damages Because of Bodily Injury”?
Our next step is to determine whether the complaints in the underlying actions actually alleged plaintiffs suffered “bodily injury” and sought “damages because of bodily injury.” Nokia contends the underlying plaintiffs alleged they suffered present injury to their bodily cells from exposure to radiation and they sought the cost of a headset because of that existing injury and to prevent further injury. The insurers contend that plaintiffs alleged only a risk of injury, did not allege they actually sustained bodily injury, and that the cost of the headset was purely economic damages and not the result of any alleged bodily injury.
Because all of the complaints involved in Samsung are also involved in this case, we find our analysis in Samsung helpful on this issue. In Samsung, we concluded the Pinney complaints alleged “bodily injury” because the complaints contained allegations of present “biological injury” — or injury to their bodily cells — each time plaintiffs were exposed to radiation emitted from their cell phones when used without a headset:
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 *391 headset, to RFR[’]s biological effects and the risks to human health arising therefrom.
[[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.
Each of the Pinney complaints contained these allegations, which stated plaintiffs were exposed to radiation and its biological effects each time they used their cell phones without a headset. As we did in Samsung, we conclude these allegations are sufficient to state a claim potentially within the “bodily injury” coverage of the policies at issue in this appeal.
We now turn to whether the plaintiffs sought “damages because of bodily injury.” We also addressed this precise issue in
Samsung,
analyzing the same complaints at issue here. In
Samsung,
we concluded the definition of “damages”
4
contained in the policies at issue in that case did not expressly include or exclude the cost of a headset as “damages because of bodily injury.”
Samsung,
Our analysis in Samsung of the Dahlgren lawsuit is also applicable here. In Samsung, we concluded the Dahlgren complaint did not seek “damages because of bodily injury” because that complaint expressly disclaimed damages for personal injury when it stated:
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.
Id.,
One additional complaint is involved here that was not involved in Samsung— the Naquin class action. In Naquin, the plaintiffs alleged:
[cell phones] expos[e] individuals to unwanted RFR and in the absence of headsets ... fail to protect users from and exposure to RFR which creates health risks and adverse effects by causing nerve damage, cellular damage, cellular dysfunction and/or other injury to humans.
*392 [[Image here]]
[cell phones] emit unseen RFR which enters the users’ brain ... exposing plaintiffs and all users to risks of damage, injury to their health and well-being and unexpected changes in their physiology ... The demonstrated risks include cellular damage and other adverse affects.
[[Image here]]
... plaintiff and other [cell phone] users are exposed to RFR which causes physical effects, changes and the risk of long term injury including the potential for very significant long term health problems.
The Naquin plaintiffs also alleged that the cell phone manufacturers’ failure to incorporate a headset design into their phones as a standard feature “unnecessarily continu[ed] to expose users to the non-apparent assault on their head, skull and brain [] due to the exposure to RFR through the antenna.” And that to avoid the impact of the exposure to the radiation on the head, skull and brain and to render the cell phones safe, the plaintiffs would be required to purchase headsets for use with the cell phones.
A liberal reading of the complaint shows the Naquin plaintiffs alleged, as did the Pinney plaintiffs, that they were injured when the radiation entered their heads, skulls and brains through the cell phones’ antennas when used without headsets. As we did with the Pinney complaints, we conclude the Naquin plaintiffs sought a headset “because of bodily injury” because they sought the headset to render the cell phones safe and to avoid further “unwanted alterations of physiology and health effects.”
We conclude the Pinney, Farina, Gilliam, Gimpelson, and Naquin complaints potentially state a claim for “damages because of bodily injury” triggering the insurers’ duty to defend Nokia in the underlying lawsuits. We conclude the Dahlgren complaint does not state a claim for “damages because of bodily injury” and that the insurers’ duty to defend Nokia was not triggered by that complaint.
3. Does an Exclusion Apply?
The insurers argue that even if the class actions alleged “bodily injury” and sought “damages because of bodily injury,” they nevertheless are under no duty to defend Nokia because several “business risk” exclusions apply to preclude coverage. We disagree. The exclusions upon which the insurers base their arguments are exclusions for “property damage to your product,” “property damage to impaired property,” and damages for the recall of the product. The underlying actions did not contain allegations of property damage to the cell phones or to “impaired property” (defined as “tangible property, other than your product or your work”) or damages for the recall of the cell phones. And the case law upon which the insurers rely involved claims for property damages, not damages for bodily injury.
See, e.g., Joe Banks Drywall & Acoustics, Inc. v. Transcon. Ins. Co.,
*393 Conclusion
Applying the eight corners rule, we conclude the trial court correctly ruled that Zurich, Federal, and National Union owed no duty to defend or indemnify Nokia in the Dahlgren lawsuit. Accordingly, we affirm that part of the trial court’s judgment awarding summary judgment in favor of Zurich, Federal, and National Union regarding the Dahlgren lawsuit.
We further conclude Zurich, Federal, and National Union owe a duty to defend Nokia in the
Pinney, Farina, Gilliam, Gimpelson,
and
Naquin
lawsuits. Because of our decision on the duty to defend, we also conclude the trial court’s ruling that the insurers had no duty to indemnify Nokia was premature.

Notes
. The first insurance coverage dispute is
Samsung Electronics America, Inc. v. Federal Insurance Co.,
No. 05-04-01316-CV,
. Four of the six complaints, Pinney v. Nokia, Inc., No. 01-MD-1421 (Cir.Ct., Balt., Apr. 19, 2001); 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); 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, violations of state consumer laws, breach of *387 implied warranties, negligent misrepresentation, fraud by concealment, civil battery, and civil conspiracy. These same complaints were the underlying lawsuits in the Samsung case. For consistency, we refer to these complaints as the Pinney complaints. The fifth complaint, Dahlgren v. Audiovox Communications Corp., No. 02-0007884 (D.C.Super.Ct., Sep. 6, 2002), asserts claims for violations of state consumer laws and unjust enrichment. It also was an underlying lawsuit in the Samsung case. For consistency, we refer to this complaint as the Dahlgren complaint. The sixth complaint, Naquin v. Nokia Mobile Phones, Inc., No. 00-2023 (E.D.La. Apr. 20, 2001), was not involved in the Samsung case. The Naquin plaintiffs asserted claims for fraud by concealment, civil conspiracy, breach of contract, and unjust enrichment.
. We quote from Zurich's CGL policies. The parties agree that any variation in wording among the policies at issue in this appeal does not affect our analysis.
. The Federal policies at issue in this case and in Samsung further defined damages, but that definition did not address the precise issue involved in these appeals. The absence of a similar definition from the Zurich and National Union policies at issue here does not affect our analysis of this issue.
