T-Mobile is the brand name used by some of the mobile communications subsidiaries of the German telecommunications company Deutsche Telekom AG in the Czech Republic, Poland, and the United States, and by the former subsidiary in the Netherlands.
I travel a lot, recently I was in Sri Lanka & I observed many people were unable to send SMS messages from my T-Mobile sim. I followed some solutions & later I was able to receive an SMS but It was frustrating. Later I also found that people were also facing Message not sent number formatted incorrectly.
I tried to tell these tips to other people, and it worked for them too. So in this, I am going to share those tips and tricks with you so that you can solve this SMS not sending or receiving issue from your side.
Fix: Unable to Send or Receive SMS on T-Mobile sim
Below I have shared the Reason behind both T-Mobile Prepaid sim and Postpaid sim Users for this issue:
Solution 1
If you have changed your T-Mobile Sim recently like me, this means the same number and same network but a new SIM(upgraded) then you will not be able to Send or Receive SMS to your number for some time as a part of security measures from T-Mobile for a few days.
In a similar case, If you got a 4G SIM replacement for your T-Mobile mobile number, you will not receive or send any SMS for the next 24-48 hours.
It means if you are using a new sim for 24-48 hours you may not be able to receive or send any SMS from the T-Mobile network, if you want more information you can contact T-Mobile support.
Solution 2
If you haven’t sent any SMS or Message from your mobile in the last 6 months then the T-Mobile sim may disable the outgoing SMS messages of your mobile number.
To Verify this case you can call T-Mobile sim Customer Care and Ask them to enable SMS Services. After a successful request once restarts your mobile to start sending SMS. Nowadays this process seems to be canceled so far in 2022. But again I request you to confirm this from customer care.
Solution 3
Your T-Mobile sim SMS Center Number might be wrong, so in this case, you can try either refreshing or updating SMSC. Remember you should use the SMSC of your area. You should choose SMSC according to the area which your country.
Steps to update or refresh SMSC:
- Dial – *#*#4636#*#* on Keypad.
- It will automatically open the ‘Testing’ settings.
- Now if you have two sims in your android phone then choose accordingly. In my case, I opened ‘Phone information1’.
- Now scroll down and try to find the ‘SMSC’ option, here will see the Refresh option tap it.
- if it didn’t work for you then type your network operator’s SMSC number of your area and tap Update.
Solution 4
If there is an incorrect Date and Time on your device then it may be a root cause of the issue and it may create other issues too. So try to fix it.
Here are the steps to set your device time accurately:
- Open your phone’s Clock app.
- Tap More and go to Settings.
- To pick your home time zone: Tap Home time zone. To automatically update your timezone: Tap Change date & time. Set time zone automatically.
- To update your timezone based on your location: Tap Change date & time Set time zone automatically.
Tip solution: Put your SIM on a different phone. If it works then the problem is with your mobile phone. Unfortunately, if it doesn’t work then try to get help from T-Mobile Customer care.
