Absolutely the worst cell service ever. They put a block on your phone with out your permission so that you cannot use it with any other service. Unlimited data with end about 3 days after the first of the month. I would have to call them four or five times a month to get my data service restarted. The Voice service didn't work more often than it did work. Didn't work at all for the last 6 weeks I was on their service. When I canceled their service I found out they had put a block on my phone so ever cell Services can't use my phone. When I called customer service they tried to get that off my phone. Then they told me there was some kind of error and they couldn't remove the block from my phone. When I got upset that they had just ruined an $800 phone they started denying they put the block on my phone. Ask your local phone carrier they know about Q Link Wireless block and how it ruins the phone for any other. This should be absolutely Criminal....
