After I received the SIM card and installed it, it took an hour online from my desktop computer and CHAT to get through the process of changing my smartphone over to this carrier. Then the rep told me he got it set up but it wouldn't be operational until the next day. The next day I tried it and it wouldn't work. After a few hours I was able to make one call then it immediately stopped texts and calls from going through at all. I had to spend another hour on another CHAT with a rep to get it operational. He was great but it now takes 4 minutes for a simple text to go out. It takes several seconds for a call to connect, which is an eternity really. It uses up mobile data at an astounding rate. Just three minutes on the internet used up 100MB. You will have to order 2GB a month just to be on the internet for one hour a month. I haven't even tried voicemail yet. I am afraid what that will be like. But I did save almost half the price of what I was paying the old carrier. And customer service is very knowledgeable and happy to help every way they can.
