I activeted a replacement phone and Sims card then I erased my replacement phone and backed up my old phone then restored the info on my replacement phone. But now somehow my phone # has changed. If I phone my # it goes to voicemail and if I text someone they don't get any sender info. Even Koodo can't seem to contact me because yesterday was the final day for my prepaid 30 days and I got no notification. How do I get my old # back?
