I travel internationally frequently. Recently, in Cozumel, I would get TelCel, the text message Welcome to Mexico, free 2G, et al. I would get 4GLTE data with the roaming on, which is normal. As soon as I get that the phone switches back to 3xxxx, which is cellular at sea. It appears the ship tower is trumping the local carrier. Is there a way to block the ship from taking over my access to TelCel or, will I be charged or not for access as I did get the Welcome to Mexico and it switched without my knowledge? I was under the impression that Cellular at Sea turns off when in port.
Not sure how T-Mobile works when a switch happens like that. I immediately turned the roaming off because cruise ships charge $15/mb.
I want the local 4GLTE and not the ships services.
I thought I replied to this yesterday.
You could manually connect to TelCel and that should stick until you lose signal and the phone re-scans for a new carrier. You might want to mention this to TelCel. They may be able to get the cruise line to stop cutting into their business. I don't think the cruise ship should be running their cellular system when in port. Maybe the Mexican authorities have decided to turn a blind eye. I don't know.
