This company must be the worst I've dealt with. They will promise you the world in credits.
One thing they don't tell you is that you'll have to wait for 4-5 months maybe longer to see any credits and will most likely be charged other charges on top. I've been calling every 2 weeks to get an issue resolved and have not been able to get a clear answer. Calling in, be prepared to wait 1hr plus to someone that may be able to help you and be patient to listen to them complaining about how busy they are instead of addressing your issue.
Coverage is terrible as well in the Bay area and the so called unlimited data is throttled so much that is useless. DO NOT FALL FOR THEIR LIES!!!
