iphone 6 can't send the international texting message

[f2a]

My plan has international texting message, I can send it on iphone 6s. But on the iphone 6 ios 10.0.2 can't. I can send texting message to local number but when I send the international sms they can't received.

I check the iphone settings but I can't see any different.

How to fix the problem?

Thanks!

The proble is solved .The reason is the number saved on the iphone 6 doesn't have the country code.

When I test it I dial the whole number, but I know why the iphone 6 deleted 011+country code. I delected the name and number from the iphone 6 contact list then the problem resolved. 

Thanks everybody !

From what I hear, international text messaging has always been a toss-up in terms of reliability.  Often, there are issues when sending text messages to specific carriers.  Domestically, I would say that SMS is definitely more reliable than sending them outside North America.  Internet-based instant messaing and chat applications are an option if you have a data plan.

@f2a Well, assuming you can make/receive calls, that confitms it's a settings issue with the iPhone 6. Here is my setup:

Settings >> Messages >> iMessage toggle on, Send as SMS toggle on, MMS toggle on, Send & Receive should show your Publc Mobile phone number (if it does not click it and add it to YOU CAN BE REACHED BY IMESSAGE AT:).

The phone number is correct, because same number test on the iphone 6s no problem. Just the iphone 6 has problem.

do you have the proper area code on the number before the phone number? maybe your old one auto did it and this does not?

Is your ios fully up to date?  I beleive the most current is 10.2.
