Need a new phone

[joed]

I have been with Visible for 3 years and I want to buy a new phone. .I have tried to buy one on the Visible web site, but it says I already have a plan when I try to buy it. Can I just get a android phone somewhere else and switch the simm out without any issues. I tried getting Visible customer service support but I will probably die before they answer. All I use it for is to hotspot a couple times a week, but the phone I have is the old R2 and it had a crack in the side. I just need a phone to hotspot a few times a week. ANy help would be appreciated.

Yes you can do it but the phone has to be unlocked. Please note that some phones will not work

Aye there's the rub, you won't know if the unlocked phone is compatible until you have then IMEI and activate. Previously I was actually able to go to Best Buy and spy the IMEI on the model I wanted to use for compatibility checking (but not activation).
