Mobile Phone Ringing Mystery

[fiesata]

I have a friend who calls his girlfriend (of two months) who apparently lives in an area with a poor mobile signal

On several occasions he has called her and hears the message 'the mobile you're calling is not available' so he tries again in 5 minutes the ringing tone is on his phone but his girlfriend says (when he speaks to her later or the next day) her phone has not rung ( it's switched on and the ringer setting is on)

Is this possible? I think she's just avoiding him - are there any knowledgeable folk who could settle this please

I'm no expert but suspect that it is the local exchange that generates the ringing tone, not the end phone. If you try phoning a nearby mobile you will hear the ringing tone before the phone rings.

He'll kill any relationship with her if he's accusatory. If he gets a chance to speak to her again. Instead of accusing her, he should suggest that she call him whenever she wishes. If she never calls, then he'll know that answer.

This sometimes happens to me when using "what's app" to call and not the phone setting

My phone gives out that message when im already speaking to someone else.
