Two questions.
Does the Verzion HTC Thunderbolt work on any GSM network like the Blackberry Tour?
Any insight would be much appreciated.
Thank you
umm to answer the question more technically,, 4G is a GSM type network hence why the phone has a SIM card. It is designed to be a world phone verizon designed the software to hide the GSM options. The phone works the same as a Droid 2 global. The biggest clue is that the thunderbolt can be SIM unlocked to work with any GSM carrier. Verizon gave me the unlock code..lol
verizon and sprint only use CDMA whereas every other carrier uses GSM. CDMA is a great signal base for phones but it offers a very narrow bandwidth. Verizon and sprint have been slowly making the transition to GSM for years. Another downside to CDMA is that phones cannot operate to CDMA signals at once and it has to do with the how the phones register on the hpone network. Inside phone like the Droid 2 Global and the thunderbolt, the SIM is mainly used for the internet connection hence why you can now talk while surfing the web. ATT has been able to do this for years because there voice service runs on GSM 800 and they switch there ISP to run GSM 2100. The change allowed the phone to truly multitask ie voice talk while web surfing. Both verizon and sprint have begun to embrace this and as such the phone do voice over the usual CDMA and data of GSM. like i stated earlier, verizon provided me with the SIM unlock code to my thunderbolt. I have unlocked it and tested it with a T-Mobile sim card and yes i could make phone calls.. Bottom like is that if a phone comes equiped with a SIM card, it means it can use GSM if it is SIM unlocked.
also cdma supports both voice and data. but vzw has just started using it on the new LG phone. it will be slightly slower but works.
