This might have been discussed much earlier and I apologize for duplicate query. I've had great experience overseas with data/text/voice on my Moto G.
And with older iPad2, got the free 200mb domestic plan when first launched. I sold the 2 and only upgraded to the newer iPad Air model, with cell/wifi -- actually got a discount via my son and picking up the Air in HK later this week.
I called TMO and they confirmed can swap for new proper size sim. I also know the monthly allowance has been bumped to 1gb. When talking with CS, they said the 1gb also works overseas? Can folks confirm whether this is actually the case? Thanks!
