If your Jio network is weak in your area, or you have found an Airtel or Vi recharge plan that suits you better, you may be thinking about changing your operator. But what about the number linked to your bank account, UPI apps, WhatsApp and other services? You do not have to change it. Mobile Number Portability (MNP) lets you move to another operator while keeping your existing number.<\/p>\n\n\n\n
To start the process, you need to send an MNP SMS (also called mobile number portability SMS<\/strong>) and get a Unique Porting Code (UPC). You then share this code with your new operator before it expires. This guide explains who can port a number, how to send the SMS and what to do next, whether you are moving to Jio, Airtel, Vi, BSNL or MTNL.<\/p>\n\n\n\n
What Is an MNP SMS?<\/strong><\/h2>\n\n\n\n
MNP stands for Mobile Number Portability<\/strong>. It lets you move your mobile number from one operator to another while keeping the same number.<\/p>\n\n\n\n
An MNP SMS<\/strong>, also called a port message<\/strong> or porting SMS<\/strong>, is the message you send to 1900<\/strong> to request a UPC. You need this code to submit your porting request to the new operator.<\/p>\n\n\n\n
The Three Messages You May See During Porting<\/strong><\/h3>\n\n\n\n
Message<\/strong><\/td>
Who sends it?<\/strong><\/td>
What does it contain?<\/strong><\/td><\/tr>
Porting request SMS<\/td>
You send it to 1900<\/td>
PORT <10-digit mobile number><\/td><\/tr>
UPC reply SMS<\/td>
Your current operator sends it<\/td>
Your 8-digit UPC and its expiry date<\/td><\/tr>
Porting update SMS<\/td>
The MNP service provider or new operator sends it<\/td>
Confirmation, porting schedule or SIM activation update<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
The first message is your request. The reply with the UPC is the code you need to continue the process.<\/p>\n\n\n\n
Who Can Port a Mobile Number?<\/strong><\/h2>\n\n\n\n
Your number must meet TRAI\u2019s eligibility conditions before you can get a UPC. If a condition is not met, your request may be rejected, and you should receive an SMS explaining the reason. a<\/a><\/p>\n\n\n\n
Order a SIM through Airtel\u2019s website or visit an Airtel store. Check Airtel\u2019s official channels for current application and status-tracking options.<\/td><\/tr>
Visit a BSNL Customer Service Centre or authorised retailer with your UPC and the documents requested for KYC.<\/td><\/tr>
MTNL<\/td>
Send the same SMS to 1900 to request your UPC. Contact MTNL customer care to confirm how to complete the application for your number.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
If you are leaving any of these operators, send the same porting SMS to 1900<\/strong> from the number you want to move. Your current operator will issue a UPC if you meet the eligibility requirements.<\/p>\n\n\n\n
Porting Timelines and Charges<\/strong><\/h2>\n\n\n\n
1. How Long Does Porting Take?<\/strong><\/h3>\n\n\n\n
The time depends on whether you are moving to an operator in the same telecom service area or a different one.<\/p>\n\n\n\n

2. Is Porting Free?<\/strong><\/h3>\n\n\n\n
TRAI says the new operator may charge \u20b96.46 per porting request<\/strong>. Some operators may waive the charge or offer SIM delivery at no cost, so check the current terms with the operator before applying.<\/p>\n\n\n\n
3. What Should Postpaid Users Do Before Porting?<\/strong><\/h3>\n\n\n\n
Pay any outstanding bills issued by your current operator. If you have a refundable deposit with your current operator, ask how it will be returned after the number is ported.<\/p>\n\n\n\n
Why Is the Port SMS Not Sending or the UPC Not Arriving?<\/strong><\/h2>\n\n\n\n
If you do not receive a UPC, check your message format and the eligibility rules first.<\/p>\n\n\n\n
Problem<\/strong><\/td>
Possible reason<\/strong><\/td>
What you can do<\/strong><\/td><\/tr>

You requested the code within seven days of a SIM swap or replacement<\/td>
Wait until seven days have passed, then resend the message<\/td><\/tr>

The code may have expired or been entered incorrectly<\/td>
Request a fresh UPC and share it exactly as received<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
TRAI says an SMS should explain why a UPC request was rejected. If the issue continues, contact your current operator\u2019s customer care.<\/p>\n\n\n\n
It is the SMS you send to 1900<\/strong> in the format PORT <10-digit mobile number> to request a UPC and start porting your number.<\/p>\n\n\n\n
