Considering the extra investment and scut work involved, it's probably not worth it for 1 month use.

Does it need more work just for iPhone or for all phones that are not branded StraightTalk but can operate in CLR and PCS bands? A 3G AT&T phone other than iPhone, for example.
I hope LTE eliminates or reduces incompatibility that prevails in the U.S. ,not only because of different technologies such as CDMA and GSM, but also different bands within the same technology (1900 and 850 MHz in the U.S.m versus 900 and 1800 MHz, in most other countries, except Japan and Korea) or different bands such as IMT, CLR, PCS and AWS.

thanks for all the info yaatri & mr. bean....from all the operators mentioned above, jolt mobile looks like one that is most likely to work....in their 'phone setup' section they have configuration settings for the iphone....

their $69.99 plan also looks quite good....unlimited talk & text with 2gb of data & some pretty good international call rates....

If you have apn, port and server names, should it not work? What else do you need other than the following? I think, MCC and MNC for AT&T any AT&T based MVNO should be the sane. It looks like only APN and MMS proxy are different.

APN: att.mvno
Proxy: n/a
Port: 80
Username: n/a
Password: n/a
Server: n/a
MMSC: http://mmsc.cingular.com
MMS Proxy: proxy.mvno.tracfone.com
MMS Port: 80
MCC: 310
Authentication type: n/a
APN type: internet+mm

Honestly, I am not sure. It seems that only certain ST phones come with the SIM cards that allow for unlimited smartphone data. The most important aspect of process seems to be about editing the carrier APN info to allow the iPhone to access that data network. I am not sure what APN info other ATT phones would have. They may or may not require further APN editing.

Don't buy Matrix SIM
 
I bought matrix SIM for my travel in Turkey. Initially I was told that incoming call would be free but when bill came, they were charged. Before I could take up the matter with customer care and find a resolution, my credit card was charged, of course with charges of incoming calls. Again, they do not say that SIM they provide is from UK. So when you are in a country, other than UK, you will be charged roaming charges. In general, I found Matrix cellular company unreliable and unethical. I advise not to use their products, or when you use them, use with extreme care.

welcome to ft drmehtasam....i can back you up on their unethical practices as i have been a victim of those as well....they also have a tendency to overcharge & then take 2-3 months to refund the charge....

the only reliable plan they had was a inr 2,999 per month global blackberry plan....it came with unlimited data & worked anywhere in the world....but they discontinued that a couple of months ago....

Matrix Sim Cards, Fraud & Cheating.
 
Beware of Matrix Sim Cards.
I'm a recent Victim of their Fraud & Cheating.
They are known to charge your credit card irrespective of having been given a Dead SIM Card for Kenya. This amounts to Fraud & cheating.
All your emails with support will not sway them in offering better customer service. Expect standard replies from then.
