Sim swap Att locked to Locked phone

[metsjetsfan]

I have new 6S+ currently locked to att and want to sometimes use an old 5S which Is ATT locked as well. Is there an issue if I move sims back and forth. Sounds like a no brainer but i wouldnt be surprised with these carriers

Thanks in advance.

It will not be an issue. I have swapped SIMs multiple times without incident. The ONLY issue you will face is whether or not the same sized SIM is used by the different devices. (This will NOT be an issue between the 5S, 6, 6S, 6+ or 6S+.)

Definitely no issue, swap away.
