GSM vs. CDMA?
Hey guys. What's the difference between Tmobile's GSM technology and the CDMA tech used by Sprint and other companies? Is one better than the other?

Just go to Wikipedia and look up CDMA and GSM. It might seem a little confusing but you can also just google the terms as well.
People tend to have their favorites, kind of like car companies, but you have to try them both out to decide which one you like best. For me, that's CDMA. 😁

the main different is the little "smartcard", that you can change phone with ease
CDMA (including UMTS), on the other side, the wave has better travelling characteristics, but it also requires more CPU power to run codec

we have been here before. CDMA is in allot of countries just not in Europe as it once was not legal to deploy cdma. CDMA is expanding quickly now. The only issue is like Japan AU uses CDMA2000 just like sprint. However there doesn't seem to be a market for a world CDFMA phone. As in Japan uses 2100 for their phones. THere are many other places that use CDMA but on a different freq and there are no phones from US carriers that have more then the 800/1900 bands used here.

gsm phones and networks are built such that anytime a device tries to access the network, the information on the S-ubscriber I-dentification M-odule (or SIM card) is verified, and the handset (or device) compatability with the network and services that are trying to be used is checked, but the device's E-lectronic S-erial N-umber (or ESN) is not checked by the network. therefore, any device (whether it has an ESN or not) can be unlocked and provided access to the carrier's network and services (the user can even get access from multiple carriers, simultaneously, provided the device has the proper software to be able to do that).
bottom line: gsm phones and networks have open handset policies because the network does not check the device's E...
