Airtel does kick you out of network after a number of years. Personal experience, had to pay 118 for new sim even when old was in phone for last 3-4yrs… I had received old one as replacement for 3g to 4g network….. sad evil

that’s what i meant, because i have 2 numbers on the same Vi network. The older sim has intermittent issues, like balance check does not work, call drops etc. so i was thinking if its time to replace the old card

Theoretically no.

But practically. They do become less effective with time.
Due to oxidation of contact pads.
Changes in sim circuit value due normal wear and tear.
Priority give to newer sim cards over old ones by networks due to some technological advancement over time.

Old SIM decades back didn’t had 4G support so most operators had to ask customers to upgrade SIM
In past operators have also upgraded SIM card with better memory (i.e 64K to 128K or so)

All depends on when have you taken the SIM…if it supports 4G ideally you should not have any issue because of SIM

For shift from 3g to 4g? Yes you need to change.
Also the newer sims have new technology. And better memory. For eg Try adding a long name in your old sim vs new sim(character limitations)
Usually sim pads get reduced/wear off if you are chindhi user like me who keeps on interchanging sims for any offer.
You won’t get super super high signal boost just because you got new sim.

2 of my Airtel nos. are not being detected in any device be it a feature phone or smartphone. Only a few years old. Originally Tata Docomo nos. upgraded to Airtel 4G after the merger. Last worked in Jan w/o any issue. Seems fishy?

Did they block the other docomo numbers?

Any last warnings?

No warnings as all are active numbers in use. Only messages to change sim. But somehow airtels old sim stopped getting signal in older featute phones.

Oh, Did you try getting them re-activated?

Is the balance 0 for them?
Was it in use for calling? incoming/outgoing

All was active, in regular use with balance. But automatically lost connection in old feature phone. Cant use them in new smart phone, so had to change sim.

In my case they weren’t detected in smartphone as well. Only recharged once every 90 days or so.
