I paid for a sim through you guys so I'd expect to have reliable coverage but not only do my messages not come through or my calls drop or become inaudible, but I still experience no difference with or without a sim card and while the sim gives the benefit of being able to call or text without wifi, (data is separate) it's not that reliable even for the paid plans. If I'm paying, why is your service still trash? It hasn't even been a year and my lock in number plan ended twice. I'm done paying.
