Hello all,
I have a Nexus 5 that I bought through FreedomPop. The phone comes unlocked, but FreedomPop says that I need to deactivate my phone and unassign it from the network by contacting them. However, I was under the impression that if you did a reboot you can swap SIMs at will. I'm going to Europe for a few weeks and I was planning on popping in a SIM from a local carrier, but I don't want to permanently cancel my service with FreedomPop. I've heard a lot on forums and stuff of people just swapping SIMs whenever. Is this thing by FreedomPop only meant for a permanent switch? Can I just pop out my SIM, use a European one for a couple weeks, and pop it back in when I come back to the US, and no one will be the wiser? Or did FreedomPop put some kind of restriction on it (even though the phone is supposedly unlocked)?

I have a sprint galaxy s5. I don't use sprint anymore because they suck. They won't domestically unlock it for me even tho I own the phone. My question is can I swap the motherboard with a European (G900F) without any issues? Thank you in advance.
