Help Swapping out sim cards - a question

[gale65]

I have a galaxy s7 using an at&t sim from straight talk. I am having a bit of trouble with signals in my area, so I got a verizon sim to try out. My phone has gsm and cdma capability. My question is this-if I swap out the sim cards to try verizon, and want to use at&t again (until my month is up, at least) is it as easy as just swapping them out? Do I have to reactivate the sim every time?

It's my understanding that once the SIM is activated, you can put it into any device that supports the necessary bands for the network. So swap away.

As long as the phone isn't locked to one provider's SIM you should just be able to swap however you fancy.

Awesome-thanks to both of you. It's an unlocked phone so it should work.

Well it didn't work. Not sure why but the verizon prepaid sim would not activate. I called support and they couldn't help so I put my straight talk sim back in. Verizon told me I would have to factory reset my phone. I was only doing this as a trial so after all the problems I've had with verizon just trying to get this sim, and now the issues with it not activating, I'll stick with ST.
