Ok, so this happens pretty randomly, and only when the person I'm calling is outside UK (roaming). Scenario: I call the other person with my UK SIM, me being in UK. The other person, outside UK, receives my call, but instead of seeing my phone number, a different number is displayed on her phone. This different number seems to have the format of the country she's in. This is happening rarely and at random, moreover, the number shown is different every time. Has anyone experienced this before? Could it be related to the way roaming works, maybe assigning a temporary number which somehow is displayed instead of being hidden? My phone is Lenovo P2 and I'm on Android 6.0.1.
