Along with other private providers in the region, BSNL is quickly expanding its 2G/3G mobile network. Both BSNL prepaid and postpaid consumers should be prepared to take lead in the development of 4G mobile technology.
In this brief post, we will attempt to clarify how to upgrade your BSNL connection to 4G and how to activate a BSNL 4G SIM card.
We previously published an article about how to quickly obtain a new or replacement BSNL SIM card. This clarification would be relevant in this context.
Why do upgrade BSNL 3G to 4G?
As the number suggests, 4G is the fourth generation of mobile communication technology, following 3G and 2G. When compared to 3G, this provides superior voice clarity and high-speed internet connectivity.
Please keep in mind that the 4G service has not yet been launched in all areas of the country, but it is hoped that it will be available in all parts soon. Check with your local BSNL customer service center to see if there is 4G coverage in your region.
Then let us discuss how to convert BSNL 3G to 4G? If you are moving to BSNL 4G SIM upgrade decision you should ensure the following points.
You must have a 4G compatible mobile device to use the 4G service. You must now swap the existing 2G/3G SIM card with a new BSNL 4G SIM card.
How to know that my mobile is 4G Compatible?
If your handset does not support 4G technologies, you will be unable to use the 4G network connectivity options. Users must have a 4G handset capable of operating at Band3/1800 MHz.
The first thing you should do here is reviewing the technical specs of your handset. If you don’t have the original specs booklet from the manufacturer, it’s not difficult to check out those specifications online via websites like GSM Arena.
If your current handset does not support 4G, consider purchasing a new mobile that does. There are decent 4G smartphones on the market at very low prices.
Customers can still see if their handset is compatible with BSNL 4G services. They would need to know their mobile handset’s IMEI number for this reason. Simply follow the steps below to find out your phone’s IMEI number and 4G connectivity.
- Simply dial *#06# from the dialer. Then you will get a 15-digit number known as the IMEI number. If your phone has two SIM cards, just consider the first one.
2. Send an SMS to 14422 with the format KYM<IMEI NUMBER>. Please keep in mind that there is no space between the letters.
3. You will receive an SMS shortly after sending the above request. If it says ‘LTE FDD Band 1,’ the handset is compatible with 4G networks.
The issue with the 4G handset has now been resolved. The next step is to obtain a BSNL 4G SIM card.
How to get BSNL 4G SIM card?
As BSNL upgrades the network to 4G, most consumers will be eligible for the free replacement 4G SIM offer. Customers in those areas where 4G is being rolled out will thus swap their SIM card with a 4G SIM card for free.
Other customers would pay a nominal fee of ₹50. This latest 4G SIM card is now available at all BSNL customer service centers as well as other BSNL channel partner/franchisee outlets.
However, it should be noted that the new SIM card will be available in either an activated or non-activated form. The activation procedure will be covered in the following segment.
How to activate BSNL 4G SIM card?
As previously said, we can purchase a new BSNL 4G SIM from the customer service center, channel partners/franchisees, or any promotional program location such as BSNL Mela.
Customers should be aware that they will either receive a paired SIM or an unpaired SIM. Most of the time, the SIM card we get from the customer service center is paired and activated by a BSNL executive.
However, the SIM cards that are available in other places may not be paired or activated.
If the SIM is already active, you can use the new SIM by switching out the old one within 24 hours of activation. Monitor to see if the old SIM has lost signal connectivity. If your old SIM card loses signal, you should swap it with a new 4G SIM card.
If you have a new SIM card that has not yet been activated, lets us understand how to activate BSNL 4G SIM through the steps below.
Step1: Send an SMS from your existing SIM card to 53734 in the format RE4G <space >6 digits SIM number <space> Circle code. Here you will get the SIM card number from the new SIM package and the circle code is as per the table shown below.
|CIRCLE NAME||CIRCLE CODE||CIRCLE NAME||CIRCLE CODE|
|ANDAMAN TELECOM CIRCLE||AN||MADHYA PRADESH||MP|
|ANDHRA PRADESH||AP||NORTH EAST 1||NE1|
|ASSAM||AS||NORTH EAST 2||NE2|
|HIMACHAL PRADESH||HP||UP EAST||UE|
|JAMMU AND KASHMIR||JK||WEST BENGAL||WB|
|KERALA||KE or KL|
Step 2: As soon as you send the message you will receive a verification message from BSNL.Here you have to confirm your new SIM card number once again and reply back as ‘RE4G<space>YES to 53734’
Step 3: In this step, you will receive another message stating that your SIM swap request is registered successfully.
Then you must wait for the swapping process, which can take up to 24 hours. If BSNL 4G activation process is completed, the signal to the old SIM card will be lost, and you will be able to swap the old SIM card with the new one.
It is important to remember that before changing the old SIM, you can back up the contacts in your old SIM to your phone or other cloud storage application. The old SIM card’s data would not be migrated to the new SIM.
How to activate 4G network settings in your mobile?
We have now done BSNL 4G activation of the new SIM and are registered with the mobile network. The following move is to configure the network settings in the mobile phone.
To do this, go to “settings” and switch the mobile network to “4G” or “LTE.” It should be remembered that most dual SIM phones have a 4G option for the first SIM slot, so a 4G SIM should be used in that slot. BSNL 4G Mobile customers will be able to make both voice and video calls over data.
