I can't send text messages to Myanmar numbers.

If your Myanmar number can't send SMS, it may be due to the following reasons:

1. Incorrect SMS center number: You need to check whether your SMS center number is correct. The number of SMS centers varies from country to country. You can find the correct center number in the mobile phone manual or on the Internet.

2. Insufficient cell phone signal or power: If your cell phone signal or power is insufficient, it may lead to the failure of SMS sending. Please make sure your phone is in a strong signal area and the battery is fully charged.

3. Sending time exceeds 24 hours: If your SMS is sent for more than 24 hours, it may lead to sending failure. Please make sure that your mail is sent within 24 hours.

4. The mobile phone has blocked the SMS sending function: If your mobile phone has blocked the SMS sending function, it may lead to the sending failure. Please check your phone settings to make sure that the SMS sending function is not blocked.

5. Blacklisted by SMS: If your number is blacklisted by SMS, sending may fail. Please contact your operator to solve this problem.

6. Insufficient number balance: If your number balance is insufficient, sending may fail. Please make sure that your number has enough balance.

7. Carrier network problem: If all the above reasons are excluded, it may be that there is a problem with your carrier network, which makes it impossible to send SMS. Please contact your operator to find out whether there is a network failure.

If you still can't send SMS, please contact your operator or mobile phone manufacturer for further help and support.
