I'm planning a few weeks in Mexico and hope to connect, likely with a local sim card. However, last time I was in Merida, Mexico, I could not connect to any network. First I tried my Koodo card, but it couldn't find a (compatible) network. Then I borrowed a sim card from a local friend's phone that worked, but it also did not connect my Samsung.
Is there something with the S4 that prevents this?
I have a Samsung S4, model SGH-I337M. It is unlocked.
Thanks for any help.
