We are sorry to hear that. If you are not able to change your provider, I advise you to request a refund. But please remember we are continuing discussions with AT&T and Verizon in hopes of finding a solution, however at the moment we cannot guarantee that Mudita Pure will work with SIM cards from these carriers. Mudita Pure will work while roaming, so if you’re e.g. from Europe and travel to the US, your phone will log into one of the local networks, including Verizon & AT&T.
