Don't spend too much time on this phone - it's a bum device. The 3G shutdown means it won't get cellular service, and RIM has announced the legacy BlackBerries (non-Android, so PRIV is fine; the others are done) will no longer work reliably. They shut down the back-end servers so the phones will lose just about all of their functionality.
The reason this issue is so fatal for this BlackBerry is it was from a time when the carriers demanded the OEM handle services like eMail and internet and had an iron grip on how custom the phone was (yep; even down to if it SIM unlockable or hard locked like VZW and Sprint BlackBerries or the infamous BS "international" unlock with hard-locked US radio). They had to do this back then not only because of the carriers but also corporate customers who demanded it (the US gov't ABSOLUTELY demanded it; no questions). Fun fact: this is why a lot of them have no cameras or an IT policy blocking them.
The consequence of all of this means these phones are also known to have residual IT policies which didn't get removed (anyone knows what you get with an iCloud-locked iPhone? De-Ja-Vu huh?). Granted, BB removal was/is easy (BDM or 3rd party tools as it was locally stored and could be wiped out) but it doesn't make sense today. Doesn't work now, KNOX, Apple MDM and Google's MDM is cloud based and follow the S/N). The way carriers operate now is one of 3 modes:
- Big 3 (AT&T/T-Mo/VZW): Customize the phone, SIM lock (60 days or until paid off) and sell in retail
- ISP MVNOs: Buy "retail" SKUs (or "blank" SKUs), SIM lock, MAYBE brand since it isn't a main business item for them; it's customer retention.
- Standalone NVMOs: Mixed; some sell the phone "locked", others sell them unlocked. Mint sells unlocked, but not all of them do; it varies. Branding varies; some mark the phone, others do not.
Nowadays the carriers stay hands-off on the phone to a large degree beyond altering it with their garbage and SIM lock (and specific ROM) to the point they just discard the problem of support on the OEM; often without doing their job. Carrier-locked phones are no longer worth it today; you lose things like unlockable bootloaders for good* in some cases (like VZW) while others let you unlock it after SIM unlocking on Pixels or re-enable it in the dev menu on a few phones from Moto; but the general rule is it's locked forever unless you get a Pixel or lucky Motorola unless you're cursed by Verizon, even OnePlus follows the two-tier rule: VZW permanent, all others released when unlocked. The only exception I see NOW is trade-in deals where the carrier will take absolute garbage that came from the son's junk bin who breaks them/tinkers with junk they do not care for to get bill credits or unlocking a supported but carrier-locked phone at a deep discount (IF you can; they love to block the attempt with a balance; again, see the comment about tying balance to credits. By the time it can be done (2.5-3 years), I'm done with it as a main phone; it's a drawer toy or trade-in garbage if it's too beaten up). You pay the same price as you do unlocked too now, with all of the carrier phone downsides too unless it's being "paid" by bill credits (which they intentionally tie to paying the phone off so you can't pay it off early and make the phone unlock ready WHILE getting bill credits, fun fact number 2; AT&T pioneered this financial trap). Why not get the phone factory unlocked in retail, and either swap your SIM over or have the carrier make you a new SIM if you need it, especially when "support" is looking for an outage (or lie) and send it to the manufacturer either by force or referring the user? Back in the days of the 2-year contract, THEY handled warranty and carriers had service centers as THEY warranted the phone, not Samsung/Google/Apple/etc.
*The Samsung U1 (factory unlocked) SKU retains the bootloader issue since Samsung ships the same phone to carriers, outside of the garbage and subsidy lock as a "U1" phone in the US; or U/1U for carrier custom versions.
So yeah, it's a shelf piece.
