Amigo U.S Has Done Better...
I have used Amigo U.S. in the past, however, our previous positive experiences was marred by the fact that one of the sim cards we rented did not work and needed to be reset prior to use. Calling customer service from out of the country to get the sim card reset was a challenge, especially considering that the phone was unusable until the sim card was reset. A local customer service number would have been extremely helpful. In addition, the supposedly unlimited data plan we paid for was, in fact, limited to 5GB per billing cycle, and apparently, we got the sim card towards the end of the billing cycle. This limitation was not disclosed up front, and there was no option to purchase additional data once the 5GB limit was hit. Amigo was unable to rectify this issue requiring us to greatly improvise in order to maintain a semblance of data connectivity for the duration of our trip.
