+1 (1) (216)116-11 error invalid number

GLA40, I went through the process that BugLip described and had success. I deleted all occurances of the number in my text message, group and single messages. Then I also deleted all phone calls with that number. Finally, I deleted the entire contact. Then, I reentered the number into my contacts, with the area code, and successfully sent a text message to the individual. I also made sure to write down the number before I deleted the number from my phone. I hope this helps.

I just arrived in Israel. 2 am. trying to contact my family who had a SIM card put In their phone. Finally got the # and have been trying to text for two hours. I got re same error message as Scott. Finally got a message through after reading this entire thread. I turned off dial assist. Not sure if that did anything. Set my region to Israel. Then I deleted all bad records. Conversations, contacts, recents, etc. I rebooted the phone and entered + 972 and the number w/out 011 in front of it. I had to add 011 in fromy of the 972 and drop the plus. I also dropped the 0. So +972 523989783 did not work but 011972523989783 did work. I had to delete, restart several times and I am cautiously optimistic but I will celebrate when I get a return text the original number my nephew gave me was just 05223989783. I had to drop the 0 which is only for calling from Israel number to Israel #. Then I added 011972 without the +. This has taken me about 3 hours of Internet research of discussion threads such as this! Thank god for the internet!

SUCCESS! I first called the number to have it in my "Recents" list; then I tried your method of deleting everything but the call log; hard reset (press power & home for 10 seconds); restart; go to "Recents" call log and "Create New Contact" from the phone number; change "home" to "mobile" in the "New Contact" page; then I tried a text which worked! I have an iphone 6 with system 9.3.5. (I refuse to update because my wife's system 10.3 has too many changes that I find extremely annoying)

This is a totally crazy problem. About half the time when I text someone new I get this error message. This is nuts. I should be able to text to any number.

I did an Apple Store appointment and after doing all the suggested work and things and re-installing my iOS I could finally text to the sample numbers that we had identified that did not work for me. Hooray. Right? Well...

...Soon after that I stopped being able to text them again. It was a temp fix. Lovely. And all sorts of new numbers errored. It's just ridiculous. My phone doesn't work. Phones today need to be able to text. I don't have time for this. Oh well.

Hi Scott - did you manage to resolve this? I am having the same issue.

I've recently moved to the USA. My iPhone was bought in Australia and I have AT&T as a service provider.

I can text US mobiles but when I try and text my family in Australia I get the above message.

Thanks,

Nicolene Lawson

You have duplicated the country code. Remove either the +1 or the (1). But then the phone number is invalid. There are no US phone numbers that start with 1. The lowest number after the country code (1) is 2, and US phone numbers are all 10 digits.

The same exact thing happens to me. Only happens with one particular contact and only when responding to their text.

Were you ever able to figure out why?

Have you bothered trying to contact AT&T?

Error invalid number. Please re-send using a valid 10 digit mobile number or valid short code.

I believe this problem stemmed from me adding a person to my iPhone’s contacts without the area code. Even when I went back into my contacts to edit the phone number with the area code, I was unsuccessful at shaking the error. Making a completely new contact and clearing the conversation’s contents didn’t resolve the problem either. The real solution, as it turns out, is to totally delete the conversation from the Text Messages screen.

To delete the entire conversation, tap the Edit button on the main Text Messages screen. Press the minus symbol next to the problematic conversation and confirm that you want to delete it. That should be all you need to do, aside from adding the area code to your contact’s phone number.

Thanks for this one! This has been driving me nuts for 4 weeks. I did create the contact without the area code. Such a hot mess for such a tiny mistake. Who knew?

This worked!!!! Thanks 😀

I was having the same problem and here is how I fixed it.

I have fixed this problem on my iphone.

1. Delete all record of the problem number that will not except text messages.

Including contact, favorites, call log, text log...

2. send a text message to the phone number manually make sure to include the area code, no 1 needed.

3. click the sms button on your home screen, then select the number you just sent the message to and create a new contact from there.

I tried this and also did what Mike Jovani suggested, but it still did not solve my problem. Any other suggestions? Thanks.

THis works!! Delete everything related to that person and start over.
