hey bros…… just try contacting the airtel care by email (use the registered one with your airtel thanks app)…

i had this issue too…but i contacted the customer support and the after answering their questions…..i got unlimed 5g with unlimited data again☺️☺️☺️)

yes the nothing OS is 🅱️hit……..they always bring new bugs and performance issues…… nothing team has hired the wrong set of developers for their OS development……

JP

SnapDark we can’t do anything about os level issues… this is the solution for that problem…

And Airtel uses 4g hardware for 5g…so that’s the reason why it shows 5g when connected to 4g…

Are you sure you’ve not reached your 5g unlimited fup limit?

SnapDark

JP I have the plan, which has unlimited 5G & yeah it’s an os level issue that’s what I’m telling, it’s not about jio or airtel.

JP

SnapDark okay… and Airtel has 300gb per month fup limit on 5g unlimited..so it’s not unlimited like jio…

SnapDark

I know about the 300gb. I’m not running a server on my device. Also This is 5G & 4G data mixed uses, not 5G alone.

I just want to State that even the Airtel has issue, some os issue are also there.

Got any thoughts on this?

CMF Phone 1 - Call audio distortion

JP

SnapDark okayy… they should optimise it… i have jio and bsnl and both works fine… you can try porting if possible… why suffer when you can solve it with minimum efforts 🫡

SnapDark

JP Btw, I got this update from the Airtel.

JP

SnapDark ohh… did they give info about 4g switching?

SnapDark

JP

SnapDark ohh… okayy…

After this update there is very network issue 5G to 4G…flicker issue before this update my network was working on 5G++ now it is only working on 5G

SnapDark

MmmmNjsjs Airtel??

MmmmNjsjs

Jio

SnapDark

MmmmNjsjs hey @JP look it’s jio now 😂

MmmmNjsjs

I’m having Airtel issues.

JP

SnapDark that + was also disappeared for me for like 3-4 days and came back… no network issue..never switched to 4g…

MmmmNjsjs if it shows 5g and you’re able to use 5g unlimited data and calls… then there is no problem…it happened with me… got fixed after some day and device restart…

I also used to get 5+ at all time…but it got 5g after i restated my phone… it stayed 5g for 2 days.. when i restarted it , it got fixed.. i didn’t face any network/call issue in those 2 days…

MmmmNjsjs

Unlimited 5G internet is working but 5G++ is not coming now and there is very network error 5G to 4G

SnapDark

MmmmNjsjs yeah that’s what they say. I hope it will be fixed.

MmmmNjsjs

Will it fix soon…!!

SnapDark

MmmmNjsjs well don’t know, but it will be fixed soon.
