How To Fix Port SMS Not Sending in BSNL
There might be multiple reasons that you are unable to send SMS from your BSNL SIM card.
Let’s find out the reasons and the solution.
#1 Reason: Deactivated SMS Service
This could be a reason for the SMS not sending. If you are not sending any SMS in the last 6 months then your SMS service can be deactivated.
BSNL itself deactivates your SMS service.
How to solve it:
- Firstly, you need to call BSNL customer support.
- Here are the numbers 1503 and 1800-180-1503′
- Call them and ask them to activate the SMS service on your number.
- They will do it.
#2 Reason 2: Wrong SMS Center Number
Sometimes SMS center numbers changed due to some reasons.
Don’t worry, you can reset your SMS Center number.
Here’s how to do it:
- First of all, go to your phone’s message settings.
- Here you can see the message center number.
- Now call BSNL number customer care to reconfirm the SMS center number.
- They will give the correct information.
#3 Reason: LTE Only
If you are using 4G/LTE only, then it can be a reason that you are unable to send SMS on BSNL. Currently BSNL running 2G/3G services only so check mobile setting network option to fix it.
How to resolve it:
- Go to your phone’s Network Settings.
- Now change LTE/4G only to 2G/3G.
- Then try sending an SMS from your BSNL number.
- If not work, restart your phone and try again.

#4 Reason: New BSNL SIM
If your BSNL is new then you can’t send SMS before 24 hours. It is very small information but useful info.
You need to wait for 24 hours, then try sending the SMS. It takes 24 hours to activate a new BSNL SIM.
#5 Make Valid Recharge Plan
I have seen many BSNL SIM card holder not recharged their number and still using their phone as secondary number and time of Porting they try to send Port SMS but it will not sent because you do’t have recharge pack.
After Jio,airtel & Vi BSNL also working on recharge pack their is no lifetime validity plan any more.
At the time of Porting make sure you have Valid Recharge plan who gives validity and SMS sending facility.
#6 Do Small Recharge of Main Balance
Many BSNL SIM card holder doing small recharge pack for porting only and still not able to send Porting SMS to 1900.
The main reason of that BSNL use main balance to send SMS not recharge pack SMS.
How to resolve it:
- Do Small Recharge of Rs 10 .
- Now send SMS it will cut balance from Rs 10.
- Now SMS will send & You will receive Porting Code.
