I've got a Note 2 I purchased from ATT and I decided to go for the T-mobile $30 unlimited data plan. I just activated this morning and filled my first month up. The note 2 was purchased full price and ATT provided me an unlock code. Well using it today I note I'm stuck on Edge speeds, asking T mobile support and looking at maps I'm in an excellent data coverage area. They say that ONLY the unlocked iphones have issues with getting 4g on T-mobile, so that shouldn't be the issue with me and they forwarded this to engineering to check on. Has anyone had any other experiences using an ATT unlocked phone on Tmobile and getting 4g? I'm wondering if the tech was wrong and if my phone is just in an unfarmed 1900 area.
