Roam Mobile...

[peacefrogdog]

I used an iphone 4s in florida in January. Worked great for text, data and voice.

I am currently in Arizona and have had no problems here using Roam on an iphone 6.

Good to know. Did your iPhone 4S run on LTE or 3g/4g?

I have used Roam Mobility a few times now and no issues. they have an online Black Friday deal which ends Nov 30 on the SIM cards.
