Will my BSNL 3G Sim Stop working if I dont upgrade my 3G sim to 4G sim?
can i still use my 3G sim in 2G mode?
my main issue is im unable to get replacement sim (4g/3g sim) due to docs issue. so i just want my current 3g sim to active in future.
pls confirm. tia.

If they shut down 2G/3G service in future then yes!

bro, as of now ur right but in future hope they don’t say compulsory we have to upgrade 3g sim to 4g even to use 2g. hope they dont deactivate 3g sim cards.

bro in this case we have to upgrade. i m aware of this situation but most likely this wont happen. only 2g and 4g/5g will be there. 3g will be phased out. infact it has already started.

They can’t say that, but 1 thing i can say that all operators including bsnl will shut down 2g/3g services in future eventually. So it’s only matter is when!. So at last u have to upgrade.
But what issue in upgrading!? confused using in 2G phone?

yes it will happen, it will cut down their investment. But they will keep 2G as u said since it will take time to make available 4G in all over India.

Lots of rural people still use basic handsets. Since BSNL is govt owned, I don’t think they will stop 2g

good question though

Jio has 4g only network, so we have seen trouble using this in 2g/3g phones

While BSNL will have 2g/3g/4g so 4g can be used in 2g phones and browsing will be 2g speed

Every sim is backward compatible.
Its SIM. JUST modular identity chip.
It depends on operator that its has those respective bands. It will work on all of them. 2g/3g/4g,
And casually speaking bsnl 4g sim also supports 2g. As they are recently giving free data so many ppl have been using it on 3g network

Valid question.

Does this really work with a basic mobile (not 2g) without GPRS feature? Only experienced ones answers pls..
