My IPhone 4s is not sending text messages to just one person. Help!

Hello, why do you test a single solution among all those proposed on this page? ...

Thanks! This worked for me. FYI I'm in the UK and was trying to send it to a US blackberry number. This was the only number not working for me and I just deleted the entir conversation in the inbox view and Tada! I can text my friend again for the first time in 6 months!

I'm confused on the part after you add the digit to the number? My boyfriend is on Sprint (no iphone) and after the update I have been unable to text him as well.

I'm having the same problem of selective message blocks but not with my BF or GF - I'm amused by all the blocks among partners.... Is Apple saying something to us? :-)

So I'm not sure what the consensus is about the strategy - I've tried the hard turn off--and back on. I hope that works!

I had same problem, I deleted all previous messages out of phone, I can now text the ones I was having a problem with

I have the same problem with iphone5 ... Except that its my wife who isn't receiving my texts. She has an old clamshell non-smart phone. I can email her from my phone and can receive texts from her. This started about a week ago.

I have deleted her contact details and re entered them, have deleted the message stream, have do e the number change thing, have reset my iPhone . No solution to the problem.

I can send and reci e both iMessages as well as ordinary texts to other phones.

What can solve this?

If you cut the iMessages service and you send a sms classic, what's happening?

No change ... my wife still doesn't receive the texts. I have set up a 'delivery receipt' and Orange tell me that the text has been delivered ... no it hasn't!

I have the same problem and have tried all of the different solutions on here and none of them have worked, have you got any others please?

I tied these suggestions too but it didn't work. So I turned off iMessage and sent the message as an SMS text message. After I confirmed that they went through then I turned iMessage back on and tried it again. It worked then.

It's SMS to the oneperson that is not working ... I have trid turning iMessage off and on and there is no difference.

Sorry ...

If you have the same problem after iPhone reset (without restoring backup!), i think it's not an iPhone problem. You can confirm by testing your SIM card in another iPhone 5, OR, If you can, send sms from web selfcare of your operator, what's happening?

If you have a 'delivery receipt', i think you can check your wife's phone, test an another. If it is the same thing, it is possible that this is a routing problem between the two operators (contact him).

No - that didn't work ... the hard reset didn't facilitate me getting a text through. I tried after the iPhone was fully reset (i.e. before any restores) and then after a restore. No change.

I can't send texts from my carrier's website.

But I will look out for another iphone 5 to try with my SIM

I have same problem and only appears to affect one contact. If I double click the message when it appears to have gone, it gives an option of "send as a text message"if you select this it goes instantly. It must be a problem in the settings but I can't see anything that differs from my other contacts. It is driving me mad!

In your case it appears that iMessage problem.

Try to:

1) Restart your iPhone

2) Deactivate / Reactivate iMessage (Settings / Messages)

3) Reset Network Settings (Settings / General / Reset)
