24 hours delay for SMS?

[EricM1]

Good evening everyone

I have a Xiaomi Redmi Note 9 with two sims.

For the last few months, I am having some weird delays when receiving SMSs.

Quite often the delay is something like 12 to 24 hours.

Obviously a problem when.

Any idea what might be the cause?

I had no problems initially...

Thanks

Hi EricM1, welcome back to the community! Thank you for posting to let us know about these issues with your SMS service. 

Just a few questions to help us identify the issue:

-Are you in the UK or Abroad at the moment?

-Does this seem to happen on any specific dates or at specific times?

-Does this happen with messages from any particular numbers or all numbers?

-Have you noticed any signal issues?

-If you remove one of the SIMs does the issue still persist?

If you can let us know this additional information we will offer further support!

All the best.

-Are you in the UK or Abroad at the moment?

I am in the UK. Initially, I noticed it in France and thought it might be because of roaming but it's the same here

-Does this seem to happen on any specific dates or at specific times?

I have not noticed any date pattern. It always happen when I use some services (payment confirmation, etc)

-Does this happen with messages from any particular numbers or all numbers?

I "think" it happens with anything asking for some kind of confirmation.
I don't use SMS much otherwise so not quite sure. I'll runa  few tests with family phones...

-Have you noticed any signal issues?
Nope

-If you remove one of the SIMs does the issue still persist?

Did not think of trying this. Will try


Another thing... I checked "Email me when someone replies" but did not get an email for your answer...
Is there something else I should do?

Thanks

@EricM1 - nothing else you should do - don't worry. 

I think this issue can happen when both SIMs are in the phone - but obviously you could provide a better answer to that. Please keep us posted on how you get on. 

Cheers, 

Ryan.

The problem was initially easy to reproduce by sending an SMS to both SIMs from another phone.

I have no beginning of explanation... but switching both SIMs just made the trick.

I do remember one that I had a replacement SIM a couple of months ago and I had inadvertently swapped them.

Never mind. No idea why but it works

Thanks for the hint!

Lovely stuff! Thank you for updating the thread, really appreciate it 🙂 

Cheers,

Damn... 

Does not work again

I thought it was fixed because I had managed to send myself SMS that appeared immediately.

Today, I applied for confirmation on some french web site using my UK phone number and have not got it yet (about an hour now).

I just triewd to send myself another SMS from a UK number and... I don't receive it either.

I suppose I'll receive both some time tomorrow.

This is quite frustrating...

Not or slow receiving confirmation SMS (especially One Time Pascodes) has become a Virgin feature over the past 2+ years

[EricM1]

This is relatively new to me. 

Only spotted this a couple of months ago...

[EricM1]

I still had not received the SMSs almost 24 hours later...So I rebooted my phone...

And then received all these SMSs in succession.

Then I tried to send myself an SMS... and again... Nothing!
