What do you mean by GSM SIM?
GSM phones make use of a SIM card to identify the user's account. The use of the SIM card allows GSM network users to quickly move their phone number from one GSM phone to another by simply moving the SIM card. Currently GSM networks operate on the 850MHz, 900MHz, 1800MHz, and 1900MHz frequency bands.
GSM (pronounced gee-ess-em) is the most popular cell phone standard, and is used internationally, so you've probably heard about it in the context of GSM phones and GSM networks, especially when compared to CDMA. GSM originally stood for Groupe Spécial Mobile but now means Global System for Mobile communications.
- All Tracfone cell phones that end with this 'G' use the GSM network, which is either T-Mobile or AT&T. GSM phones have been very popular with Tracfone, but recently there has been a wave of Android smartphones for Tracfone and they all use Verizon CDMA service.
- AT&T uses GSM technology, just like T-Mobile. Verizon and Sprint, on the other hand, use CDMA, which stands for Code Division Multiple Access. All it means is that Verizon can pile on several people to use its network at once.
- Boost and Virgin are owned by Sprint, which run on the Sprint CDMA network. There's no GSM network for any of them. Verizon is the other carrier with a separate CDMA network. T-Mobile and AT&T each have their own GSM networks.
A PUK code is a number associated with your Ting GSM X1 SIM card that unlocks your SIM if it's become locked. The PUK code is printed on the credit card sized card that you pop your Ting GSM X1 SIM card out of when you first receive it.

- US Mobile currently only operates as a GSM network. This means that unlocked phones from other American GSM carriers will work on US Mobile's network. On the other hand, Verizon and Sprint are CDMA carriers. CDMA carriers don't use SIM cards and most CDMA phones are locked into their network.
- Straight also uses At&t towers. The boxes for those phones have GSM on the front, the verizon ones have CDMA or nothing. It's owned by TracFone. If the phone has a C at the end of the name of the phone (after the number) it works on Verizon.
