There was a time when changing mobile phone providers inevitably meant changing phone numbers. My husband and I did it several times, and it was always a huge hassle. Calling everyone to let them know that we had a different number was an all-day process, and we always ended up missing someone. Sometimes, we didn’t realize our oversight until months later. It caused not only missed calls, but hurt feelings as well. I am so glad that things are different now. If a person wants to change providers, they can do so and continue to use the same number. All it takes is requesting a free Pac code.
