BSNL has started 4G VoLTE Services in some part . The state-owned company initially launched 4G VoLTE Services for pilot testing in Kerala. At present, BSNL 4G VoLTE services have started in few locations in different states like Kerala, Gujarat, Maharashtra, Jharkhand, Karnataka, Telangana, Andhra Pradesh and Chattisgarh. If you are a BSNL customer, you should know how to upgrade BSNL 3G to 4G Sim Card.
I will explain different ways to help you upgrade your BSNL 3G Sim Card to 4G Sim.
How to upgrade BSNL 3G to 4G SIM Card by SMS
BSNL has simplified the process of upgrading your SIM from 3G to 4G to make it convenient for their customers. You can now upgrade your SIM to 4G simply by sending SMS. The only thing you should ensure before using this method is to check whether your KYC (Know Your Customer) process is complete for your BSNL account. To upgrade your SIM from 3G to 4G, you should first complete the KYC process. Otherwise, your request for upgrade will not be accepted by BSNL.
Now, let’s see how the SMS method works.
Check whether 4G VoLTE Services are provided in your area by BSNL.
Check whether your SIM is 2G or 3G or 4G. Most of the SIM Cards issued by the telecom provides are 4G SIMs only. So, if you already have 4G SIM, you might not need a new SIM. You can upgrade with your existing 4G SIM only.
If you don’t have 4G SIM Card, you should buy the same through SIM-Swap from nearest BSNL Centre or BSNL Channel Partner (Franchisee). Normally, the cost of 4G SIM Card is Rs. 20/- only. If there is any BSNL Mela event running in your area, you can get the SIM Card free of cost from such event as part of their promotional activity.
After swapping your 2G/3G SIM Card to 4G SIM Card, you have to start the process of activating your 4G SIM using the SMS method.
Open your Messaging App
Type in the Message in the following format: RE4G . I will show you with an example for better clarity. Assume that you live in Kerala and you have received a new 4G SIM Card with 19-digit number 1234567890123456789. To activate 4G Services on this SIM, you should send SMS with text “RE4G 456789 KL” where RE4G is the fixed text, 456789 is the last six digits of the new 4G SIM Card and KL is the Circle Code for Kerala.
You should send the SMS in the above format to 53734 using your existing BSNL Number with old SIM.
You will receive a message “Dear Customer. This connection will stop working within 15 mins of SMS RE4G < space > YES to 53734. Please send ‘YES’ only if you have received new SIM card: 1234567890123456789 and it is with you”.
Verify the SIM Card Number received in the text message with your new 4G SIM Card to check if it is matching.
After receiving the above message, send an SMS with text “RE4G YES” to 53734.
You will receive a new message from BSNL “Dear Customer, your request for 4G SIM swap registered successfully. Please check after 1 hour to get the services on new SIM issued”.
After some time, you will receive a new message from BSNL before disconnection of your old SIM – “Dear Customer, your request for SIM swap has been registered in Sancharsoft with …… (CSC or franchise details from where you got the new SIM). If request is not submitted by you. Pls report to them immediately to stop it.”
Now, wait for the network signal on your phone with old SIM to disconnect automatically.
After the network signal disappears in your phone with old SIM, replace the same with new 4G SIM Card and switch on the phone.
Your have successfully activated BSNL 4G VoLTE Services on your phone.
Upgrading to BSNL 4G by visiting CSC / Channel Partner
The process is as follows:
Visit your nearest BSNL CSC/Channel Partner.
You have to complete the required formalities for issue of new 4G VoLTE SIM Card. If KYC is not done, KYC Process should also be completed. Carry your Proof of Address, Proof of Identity & Aadhaar Card along with you.
After completing all the formalities, you will get the new 4G SIM.
BSNL will send you a Pre-formatted message in your current BSNL Number for which you requested the new 4G SIM.
You have to send this Preformatted message (Message format would be like ” RE4G 1234567890123456789 50″ where RE4G is fixed text, 1234567890123456789 is 19-digit SIM Number and 50 is Circle Code for Kerala) to 53734.
BSNL will send you a confirmation SMS regarding your request.
BSNL will activate the 4G SIM in short time.
