*802In 2013, defendant Thomas Grzymski pleaded guilty to possession of heroin for sale and admitted to two sentencing enhancements under Health and Safety Code 1 section 11370.2 based on previous convictions for drug-related crimes. The trial court imposed a "split sentence" of 10 years, under which part of the total term would be served in county jail and the remainder would be served on mandatory supervision. (See Pen. Code, § 1170, subd. (h)(5).)
Over the next four years, Grzymski repeatedly violated the terms of his mandatory supervision. In a second prosecution in 2015, he admitted to transportation of methamphetamine and two additional sеction 11370.2 sentencing enhancements. The trial court imposed a split sentence of 10 years to run concurrent to the sentence in the first case. And in a third prosecution, which led to the November 2017 order from which Grzymski now appeals, the court sentenced him to 16 months in prison on weapons-relatеd offenses, terminated mandatory supervision in the first two cases, and ordered that he serve the balance of the 10-year split sentences in prison.
Meanwhile, Senate Bill No. 180 (2017-2018 Reg. Sess.) was enacted in October 2017 and went into effect on January 1, 2018. The bill limited the reach of section 11370.2 by authorizing sentencing enhancements only for prior convictions that, unlike Grzymski's, involved using a minor to commit drug-related crimes.
Grzymski was sentenced to a total of six years as a result of the section 11370.2 sentencing enhancements. On appeal, he contends that these enhancements must be reversed. The parties agree thаt Senate Bill No. 180 is retroactive, meaning that it applies to judgments that were not final when it took effect, under In re Estrada (1965)
FACTUAL AND PROCEDURAL BACKGROUND
The relevant procedural history spans several years and involves three cases. In September 2013, Grzymski was charged in case no. CR1303138B with felony counts of possession of heroin for sale, possession of methamphetamine for sale, and possession of metal knuckles, and a misdemeanor count of possession of a smoking device.
Under a plea agreement, Grzymski pleaded guilty to possession of heroin for sale and admitted to the 2007 conviction and one of the 2004 cоnvictions. The remaining counts and allegations were dismissed. In December 2013, the trial court sentenced him to a total term of 10 years, composed of the upper term of four years for possession of heroin for sale and consecutive terms of three years each for the prior convictions. The court imposed a split sentence under which he was to serve two years in jail and eight years on mandatory supervision.
Grzymski was released from jail and began his term of mandatory supervision in July 2014. The following January, his mandatory supervision was summarily revoked after the probation department filed a рetition to revoke based on various violations, including his arrest earlier that month. As a result of this arrest, in March 2015 he was charged in case no. CR1500452 with felony counts of possession for sale of methamphetamine and transportation of methamphetamine.
*804Under a plea agreement, Grzymski pleaded guilty to transportation of methamphetamine and admitted to two of the prior convictions, although our record does not reveal which ones. Thе remaining count and allegations were dismissed. In August 2015, the trial court sentenced him to the upper term of four years for transportation of methamphetamine and consecutive terms of three years each for the prior convictions. The court imposed another split sentence under which hе was to serve four years in jail and six years on mandatory supervision, concurrent to the sentence in the first case. In the first case, *516he was ordered to serve a concurrent term of 180 days in jail and his mandatory supervision was reinstated.
A year and a half later, in February 2017, Grzymski's mandatory supervision was again summarily revoked after the probation department filed another petition to revoke based on numerous violations. Grzymski admitted to the violations, and the trial court reinstated his mandatory supervision on the condition that he serve 364 additional days in jail. That May, his mandatory supervision was summarily revoked yet аgain and, after he admitted the new violations, reinstated on the condition that he serve 364 additional days in jail.
Finally, in October 2017, Grzymski's mandatory supervision was summarily revoked one more time for additional violations, including offenses leading to the filing of the third case against him, case no. CR1704050.

DISCUSSION
Although this case's procedural history is convoluted, the issue we must resolve is straightforward: when does a split sentence imposed under Penal Code section 1170, subdivision (h)(5) ( section 1170(h)(5) ) become a final judgment for retroactivity purposes? Grzymski claims that once the trial court "modifiеd" the sentences imposed in 2013 and 2015 to eliminate the provision for a term of mandatory supervision, they were "no longer" final judgments under Estrada . We are not persuaded.
*805In general, statutes are presumed to operate prospectively. ( People v. Brown (2012)
In 2011, the Legislature enacted the Criminal Justice Realignment Act, under which certain "low-level felony offenders ... no longer serve their sentences in state prison" but instead "serve their sentences either entirely in county jail or рartly in county jail and partly under the mandatory supervision of the county probation officer." ( People v. Scott (2014)
The question of when a sentence becomes a final judgment under Estrada is a question of law that we review de novo. (See People v. Arroyo (2016)
The fact that the trial court suspended execution of a portion of Grzymski's sentences does not affect our conclusion, which is supported by the treatment of analogous sentences in the probation context. In McKenzie , the Fifth District Court of Appeal addressed when an order granting probation is final for purposes of determining whethеr a defendant is entitled to relief under Senate Bill No. 180. ( McKenzie , supra , 25 Cal.App.5th at pp. 1211-1213,
A split sentence involves suspending execution of part of the sentence, and Grzymski offers no cogent reason why McKenzie 's logic should not control. He argues that "finality for the purposes of taking an appeal ... is not necessarily the *518determining factor in assessing finality for purposes of Estrada retroactivity." But the decision he cites merely reflects, consistent with McKenzie , that an order of probation suspending imposition of the sentence "is 'deemed to be a final judgment' for the limited purpose of taking an appeal therefrom" and "does not have the effect of a judgment for other purposes," including Estrada retroactivity. ( People v. Superior Court (Giron) (1974)
Camp does not advance Grzymski's argument. Even if a trial court has authority to terminate mandatory supervision without ordering that the suspended portion of the sentence be served, as Camp held, it does not follow that the sentenсe is therefore not a final judgment under Estrada . It is settled that an unappealed order of probation suspending execution of the sentence is final for retroactivity purposes after 60 days, yet such orders are still subject to modification under Penal Code sections 1203.2 and 1203.3, the same statutes that govern thе modification of orders imposing split sentences. ( § 1170(h)(5)(B).) And when a trial court sentences a defendant under Penal Code section 1170, which applies not only to split sentences but also to determinate sentences more broadly, under certain circumstances the court may recall the sentenсe within 120 days of a commitment and resentence the defendant. ( Pen. Code, § 1170, subd. (d)(1).) But again, the possibility that a sentence may be recalled does not affect its finality.
We recognize there is a potential distinction between probation orders suspending execution of the sentence and orders imрosing split sentences that involved a trial court's ability to change the length of the overall term when supervision is terminated. When probation is terminated and an order suspending execution of the sentence is revoked, the trial court must "commit the probationer to prison for the *519term prescribed in thе suspended sentence," based on language in Penal Code section 1203.2, subdivision (c) requiring the previously imposed judgment to " 'be in full force and effect.' " ( People v. Howard (1997)

DISPOSITION
The November 8, 2017 order and judgment are affirmed.
We concur:
Margulies, J.
Banke, J.
Notes
The charges were brought under sections 11351 (possession of heroin), 11378 (possession of methamphetamine), and 11364.1, subdivision (a) (possession of smoking device), and Penal Code section 21810 (possession of metal knuckles).
The 2004 convictions were under section 11379, subdivision (a), and the 2007 conviction was under section 11378.
Grzymski was also sentenced on three other pending matters to concurrent terms of three years per case.
The сharges were brought under sections 11378 (possession for sale) and 11379, subdivision (a) (transportation).
The allegations were made under section 11370.2, subdivision (c). In addition to the same 2004 and 2007 convictions alleged in the first case, the other convictions alleged were the conviction under section 11351 in the first case and a conviction under section 11378 in one of the other cases resolved at the same time as that case was resolved.
As to the three other matters resolved with the 2013 case, the trial court ordered Grzymski to serve concurrent terms of 180 days in jail and reinstated his mandatory supervision.
We do not discuss the third case in detail because Grzymski does not raise any claims involving it.
