Question

Cannot send text - ,sometimes they receive it several times

Hi,

A while ago I switched from monthly to prepaid and since there I’ve had issue with my texts, but it’s just getting worse and worse.  I have an iPhone.
Most of the times it tells me it cannot be delivered. A friend of mine got it 4 times anyway. 
I haven’t received any text from a group text for days. 
I received a text 5x from someone else. 

 

It’s like I never know whether my text has actually been sent or if I’ve missed some. 
I tried everything with turning of iMessages, deleting the number from iMessages, deleting and activating RCS again. Koodo number is always “waiting for activation” and switched off every time I go back to the RCS option.

I have two SIMs, and I am not using my Koodo one for data. Every time I go back into iMessages setting, it tells me my Koodo number is deactivated in Data, offers me to delete it from iMessages - below that my Koodo number has a loading wheel that keeps going on, while my email address is checked. 

When I tried ti deregister the Koodo number from iMessages it tells me it is not registered with iMessages. 

Calling works.

Just to confirm, does your prepaid plan include data? And is your other SIM with another carrier, or the old Koodo monthly SIM? If it's the old one, only the new prepaid SIM should be turned on.

I wonder if data is the issue here. Group texts go through MMS or RCS, and unlike plain SMS those need mobile data on the Koodo line. RCS also needs a Koodo prepaid data plan or Wi-Fi, and iOS 18.1 and up https://www.koodomobile.com/en/help/rcs-messaging

 

As well, check that Send as SMS is on in Settings > Apps > Messages, so a message that fails as iMessage falls back to a regular text. Then turn iMessage and FaceTime off, restart, and turn them back on so the Koodo number re-registers. If it's still stuck, reset network settings.

A Koodo customer, opinions are my own.

My prepaid plan so far had 500Mb of Data, will have 1Gb stating mid-November. 

The other SIM card is a French plan/number. My phone does show the former 2 I had. No way to delete it. But shows as not active / not connected.


but I also get the “could not delivered” with a simple text. I sent one to my friend 20 min ago, it worked, replied, worked and now I replied and it tells me “message cannot be deliveeed”. Yet I’m pretty sure she got it. 
 

and then RCS, every time I go into the setting it shows this: “waiting activation”
