I've been on it for about 3 months now and am very happy with it. 5 lines for $100 a month. That $100 includes all fees. 2.5GB per phone/mo, then throttled. Runs on ATT network but speeds are limited to 8mb, that's plenty for what I do.
I bought 5 free after rebate phones from Cricket and sold them on ebay, never opened them. The Sim card was separate in the shipping box. I hate rebates, but they went through without any problems. At the same time, I also bought 5 LG G2's on ebay, new, unlocked. They were ATT phones, so they didn't need to be unlocked. Very pleased with the G2. It is 2 years old, but comparable to the HTC M8.
The savings is really when you get to 4 or 5 phones. If you only have 1 or 2 phones, you can keep them on separate accounts and pay $40 each ($35 with autopay).
If you decide to go cricket, I can send you a referral. We'd each get $25.
