An internal AT&T memo obtained by BGR reveals that company is beginning the switch to 4G compatible SIM cards for its upcoming LTE data network.
With the upcoming rollout of LTE data network, we will be transitioning our current SIMs to those that will also support LTE devices. During the transition, COR locations may carry or encounter up to eight different SIMs. It is important to use the correct SIM for the appropriate device. Verify the SKU which is printed on the SIM card as the various SIMs are similar in appearance.
Look at the SIM card, it say for all phones except the iPhone 4. You can ask does that also exclude the 3GS, 3G and original since it does not specify.
It doesnt work for iPhone 4 because it uses microsim and not standard sim. The image above shows standard sim. If its a microsim version then it should work for the iPhone 4.
Thanks, Just got the iPhone 4 and didn't even thing of Microsim.. Wish it were the ONLY phone I had to keep all up to date.. Entire office full... THANKS!.. The iPhone is Mine, should get more into it soon when Everyone Else is happy.. Right..
