Tracfone/Net10 both offer the choice of GSM and CDMA, so there is no reason to suggest that they have not decided to go with this company wide by now including ST.
Foreign cdma networks allow sim like cards called ruim cards NOW. China and India's Cdma networks would get slaughtered by limited byod if they didn't have a way to compete with their gsm brethren...The US is one of the few countries that seems to love to lock it all down for the money...or at least tighter then other countries in general...
I called ST and asked about the GSM roaming and I was told that when I purchase a GSM phone I will either be placed on AT&T or TMo but there is no roaming between the two and you can not choose the one you want, the rep said that system will put you on the one that has the best signal to the physical address that it is registered to. I was thinking about switching but as a truck driver I am worried about coverage since I go to the major cities and rural areas, I wonder how AT&T would work for me? I currently have verizon and have good coverage with their roaming agreements but take the roaming agreements away and have ST CDMA coverage I would be in trouble in KY an WV. I live in Cinci and WallyWorld has the T401G on the shelf but I don't know if I should take the risk of not getting good coverage.
I have had very good coverage with AT&T while traveling with Tracfone and Net10 phones (constant coverage aand no dropped calls). I have been less successful with T-Mobile as the provider on Tracfone and Net10. I Have only traveled thru Texas, Oklahoma, Kansas, Missouri, Arkansas, Louisiana, Tenn., Miss. and Alabama.
I also wonder if looking around for the LG GSM phone might be a better choice. Shurely others will disagree.
Warning: Call ST three times, speak with different CS`s and you might get three different answers. They handle calls for ST, Tracfone, Net10, Net10 Unlimited and Safe link, and can get the companies and the Info. mixed up, in addition to not being very well trained to be knowledgable.
They are all transitioning to LTE which in reality is neither since its not evolutionary. It depends on what layer you are describing also. Some of these standards work together and some do not.
In laymans terms cdma as people know it is being replaced by a cascade of standards that looks more like gsm with a sim card. The phones will have to have a fancy radios to be backwards compatible and it will be years and years before we can take an AT&T phone and swap a Verizon sim into it if ever.
It is as you pointed out difficult to pin point thats for sure. Qualcomm has some patents in the LTE game I believe also.
Both GSM phones are now available on the Straight Talk Website: http://www.shopstraighttalk.com/bpdi...&market=COGSM4

Pic a zip and view the ST corresponding market and its offerings.
What I saw makes me wonder if T-Mobile is in the mix.

PLEASE figure out how to unlock these sim cards to work in any unlocked GSM phone.
Everyone on HF.
Has anyone figured out how to use the FM radio on the LG 620? My phone ask me to attach the the headset(antenna).
