I am with you. Over dinner last night we had a cell phone discussion with 3 other locals. Now, he may not be correct but whoever the other carrier is here supposedly does not have an expiring SIM card like Chippie/UTS. At least that is according to a local taxi driver. I put $ on my top up card so I am good for a long time as long as they stay in business.

I just checked the website and it indicated an expiration date of 12/28/2019 while calling #191# indicates 1/10/2010. Go figure.
