This is a bit complicated, but my husband and I both have unlocked phones. He took my old sim card with his phone to Cuba and is texting me to my phone which has a new SIM card for Mexico. For some reason I'm not receiving his calls or texts but he can get mine. I'm the only person not receiving messages from him. Does it have something to do with it being my old SIM card? How do we make it work? We bought an expensive travel pack so he can reach me, but so far it has been useless. Thanks for your help!
