Problems with text messages

[Anonymous]

For the past week every text I send to a particular number is not being received by the person. She rang O2 and was told the problem lay with me. Every other text message I send to other people is being received so why is this and what can I do? Thanks

Ask them to check their blocked number list.

Hi @Anonymous , what phones have you and your friend got? Can you make voice calls to her?

If not in blocked, if your friend has an Android phone take a look in their spam folder, they may be in there.

They have definitely blocked your number by accident. ...

Make sure you've not added them accidentally too.

I have iPhone 4 and my friend has got a Samsung I think, she changed it a couple of months ago

It's the Samsung 99.9%....

Just tried to ring her there and got put straight to voice mail so it looks like she's blocked me, hopefully cos her phone is new and it's been an accident!
