Do i need to have roaming pack to receive text message
I am confused with mixed reviews. So, i will ask straight question "If i just need to receive and read the text, do i need any roaming plans during international trips" P.S. Not worried about incoming/outgoing calls or outgoing messages.. only want to read the received messages.
New phone in Mexico
I had to buy a new phone (unlocked) while I was in Mexico which came with an ATT sim card. While standing at the counter watching the ATT sales person get my phone ready I told her that I had a T-Mobile SIM card which still worked (thankfully it was not damaged in the broken phone). She finished setting the phone up and then switched the ATT SIM card with my T-Mobile SIM card. Everything seems to be working, I am receiving calls and texts from my regular number. So what's my question? Well, am I okay on the new phone? Am I using the T-Mobile service (it appears to be that way). Will I still have international (i,e, Mexico) text, data and phone? I'm a bit nervousabout this, hence the questions to the community.
