Cell phones do not work in Colombia. Colombia has a GSM network
[QUOTE=MojoBandit;2537753]Mr E was talking about his T-mobile plan, not a local SIM, so many posts since then that it gets convoluted.[/QUOTE]Which Networks Are CDMA?
Of the five most popular mobile networks in the United States, Sprint, Verizon and Virgin Mobile use CDMA. T-Mobile and AT&T use GSM.
Since GSM and CDMA are incompatible with one another, you can't use a Sprint phone on a T-Mobile network, or a Verizon Wireless phone with AT&T. The same goes for any other mix of device and carrier that you can make out of the CDMA and GSM list from above.

Technically Verizon uses both technologies, it is way more complicated than that lifewire article makes it out to be. Starting in 2010 Verizon started using LTE (GSM) for data and only relying on the old CDMA network for voice. Since that time though Verizon has been phasing out their CDMA network: there is way too much info for me to post so here are two articles you can read, the Verizon article is of course specific to CDMA as it pertains to Verizon.

This is Verizon addressing the phase out of CDMA.

T-Mobile is going to shut down the old Sprint CDMA at some point.
