Android Text Message Not Sent

vote 4 down vote favorite I'm trying to send an SMS with Messenger on my new Nexus 5X running Lollipop, but sending always fails with Can't send message on card 1, error 21. Receiving SMS and making phone calls works fine. What's going on? sms system-error google-messenger share|improve this question asked Jan 10 at 1:06 jpatokal 141116 2 Please check message service center settings for SIM1/2 and uncheck use same service center for sending/receiving messages in Message settings. android text message symbols This is the most common problem if everything else is fine. –MANI Jan 10 at 2:59 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted Most likely the destination phone number is formatted wrong, which can happen particularly when importing contacts via third-party tool. In this particular case, I used My Contacts Backup for iOS to export my contacts to VCF, then imported from Gmail. In the process, some numbers were wrongly formatted as +61 0 4xx when they should be just +61 4xx, causing the highly uninformative error message above. (The 21 error code actually comes from the operator's network, and has nothing to do with Android as such.) Removing the extra 0 solved the problem. share|improve this answer answered Jan 10 at 1:06 jpatokal 141116 add a comment| up vote 0 down vote If above mentioned methods are not working, you may try installing 3rd party SMS applications (eg., EvolveSMS) instead of Google messenger.

and finally found the solution … Whenever I android text message ringtone use an Android device I need to “fall back” to plain free android text message spy app old SMS messages instead of iMessages. This did not work on the Sony, the Nexus nor the freshly http://android.stackexchange.com/questions/133853/what-does-cant-send-message-on-card-1-error-21-mean arrived One. Logically, I blamed Android which might have been a bit hasty.After spending an hour reading through hundreds of forum post and help desk threads, it got clear, that “error code 21” means, that the operator rejected http://danielkbx.com/post/92523168124/sms-error-code-21 the submission of the message. Since my operator (T-Mobile D) never did so using the iPhone it must be related to the SIM cards I use. T-Mobile marks your SIM card being the major messages card. If you have multiple SIM cards for the same phone number as I do, you need to change the card which is currently active for handling messages. This is pretty easy, simply call *222# from the device you want to be the SMS device. After doing so, SMS worked instantly. Android, I apologize.
