3T doesn't have any other combination than 40C. It's like Redmi Note series these days. It's quiet old device. As Vi doesn't have band 40 spectrum(Except two three circles), you won't get speeds on such old device.
What will happen to the old m2m sims that works only on 2g from these companies?
Buy anything between Nothing phone 1 and Xiaomi 11T Pro if 30K is budget. 11T Pro is best when it terms of CA and MIMO. Just like Moto Edge 20 Pro.
Even though A73 supports way more combos I don't suggest it for stuttering nature in UI. Plus A7* series don't get updates as quickly as A5* series. But camera and battery life is pretty good. Just sluggish performance makes me not recommend this.
Stay away from Nord series. Good for nothing phones.
I have no idea. Airtel has decided to shut it down by 2024.
I have Realme 8, a phone which doesn't have ANY kind of CA. Even I get 60Mbps in nights and 20-30 Mbps during daytime on Vi even in peak hours in the city. It switches to 2G very rarely on it. But on my Pixel 4A which has another Vi sim, it keeps switching to 2G every single day and I need to turn Airplane mode On and Off to go back to 4G once a day. So, it depends on handset configuration and software too.
Yes Realme 8 doesn't have any kind of CA. The problems he mentioned must be where 3G is still active. Once 3G is shut down by Vi, those problems will get solved I believe. Also you seems to have uncapped sim mostly. Sims in priority circles are getting capped at 21Mbps. Even postpaid ones. So I don't want to comment on that either. Maybe after month or two they might remove this cap.
Yeah. They had capped mine to 30Mbps for a few months earlier.
