Automatic sim sending an unknown text message

Probably this is working for me since yesterday. I haven't got the flash message yet.

SMS "STOP ANOW" to 58234

This deactivates airtel now.

Hey, I believe it’s the SIM related issue, when I put the problematic SIM (with which I was get this alert) on my android phone, still I faced this issue, it’s just that I was not getting any flash alert on android device, but I have been charged for SMS getting sent. So I could narrow down it to SIM related issue, so decided to go for MNP.

Switched to e-sim and the problem went away, however I am unable to use HDFC upi as the app refuses to recognise the e-sim as a valid sim.

Greetings shrikant1303!

Looks like you are having some trouble with a popup message stating your SIM sent a text message. We can absolutely see how that would be confusing and want to get it resolved. You have done some awesome troubleshooting so far on this issue as well! Let's make 100% sure there is no carrier settings update available. When you checked for the update previously by going to Settings > General > About, were you connected to Wi-Fi or were you on cellular data? Try using the opposite network from the last time you tested and waiting on that settings page for a minute to see if any updates appear: Update your carrier settings on your iPhone or iPad.

If no update appears and this issue continues, reach out to our direct support for more help: Get Support.

Take care!

if you have old iPhone, change the sim, wait for carrier update. if its pops up for update, otherwise got to settings -> about to get it updated.

This is related to carrier issue and by swapping sims, I'm trying to update the carrier setting.

Check if MMS messaging is on or off. Mine was on and have turned it off now. Will observe if that makes as difference.

settings>Messages> mms messaging > toggle off.

After trying a lot of options like turning off imessages, Facetime, talking to Airtel Backend, etc. nothing seems to work and the message keeps on popping.

Airtel passed it on to Apple and seeing that a lot of people on Reddit with different carriers worldwide, are facing the same issue, it could be on Apple. Most of them are on dual sim iPhone 12's.

Airtel asked me if I had the same problem on my previous phone and when I said no, the only thing they could narrow it down was on the new phone. I don't want to move on to an esim, just for the convenience of a physical sim. I will wait for an iOs update, if that doesn't help, will move to an e-sim and if that too doesn't solve, will consider changing the operator.

Are all affected people using physical sim cards or this happens even with an e-sim?

Mine is resolved after switching to an eSim. No pop-up for the last 8 days. Maybe after a month or two, will try to move back to a physical sim, just to verify if it changes anything.

I converted my one and only Airtel sim to an esim last evening. Lets see how that plays out. I tried to send ANOW to 58234 and nothing happened on my postpaid number. No confirmation/rejection. Infact, I had sent STOP to 155223 and I got a revert mentioning that flash messages are already disabled on my number. So , this pop-up has nothing to do with Flash messaging.

For anyone that is still following this. The text message from the sim card, is asking for permission to install the APN / MMS settings/software, whatever it is called.

On my LG phone, after the install, says "Your mobile device, is now configured for WAP Browsing GPRS, MMS, GPRS.

The iPhone shows the text asking for permission, but after accepting it, The iphone does nothing.

Turns out i am still getting these flash pop ups. I restarted my phone and they are back. Swapping sim today.

Did you got resolution after swapping sim.,

Sir even I face the same issue since I was a android user and moved to iPhone now and I get this message frequently. I called Airtel and they said to remove broadcast something I asked her to do that and she said to go to Apple store . Too much. I have checked all videos related to this error. I think changing the SIM card can help . Let me know if you found a solution.
