To think they’re charged their number?

[whatseriesnext]

I haven’t spoken to my sister for 5 months. I tried to call today and it went straight to voicemail “welcome to the O2 messaging service, the person you’ve called is unavailable, leave a message”

I have a new number (my phone was stolen a few weeks back) so I’m not blocked. She’s also not someone who ever has her phone off.

I’ve tried yesterday and today with the same result.

It's also possible that if you changed your number without telling her, she's been messaging/ calling your old number in the last few weeks and thinks you've been ignoring her.

Simple suggestions that have already been made multiple times (have you tried ANY of these?):

1. Leave a message on the voicemail
2. Text her with your new contact details
3. (Gasp) put pen to paper and write her a note with the new contact details and post the letter.
4. If you're in a reasonable distance, go round to her last known address and try to speak to her!

She has blocked you ?

So the OP would rather argue with posters here than actually do anything obvious - so obvious that it didn't need a post. Yeah right. I think what is obvious is nothing to do with phones.

She was living with her boyfriend but they’ve broken up and she moved out. I don’t know where. Were also a long drive from each other so I don’t know who her circle are in that area.

But you still haven't said whether you've tried to text her or leave a voicemail!

OP, we obviously don’t know the full details of your relationship, but unless you answer the basic questions people are asking, it’s hard to understand why you’re not trying the simple things. Right now, the advice you’re getting is being met with a bit of defensiveness but you came here for help.

1. You said she lived with a boyfriend but they’ve broken up. Could you contact him, or if you’re really worried, go to his place? See if he has any details?
2. Does she have any friends you could reach out to?
3. Do you know where she works?

If it really is a dead line, then it sounds like she’s changed her number. No point in continuing to try that way.

Have you done any of these things OP? People keep asking and suggesting but I think you’ve got a bit side-tracked getting cross with other posters.

Edited to say - I see you did actually answer this post but you still didn’t say if you’d tried all these things.
