RCS Messaging on iPhone iOS18

AS1992 — Wed, 18 Sep 2024 23:05:32 GMT

Hi Everyone,

I am having an issue with RCS on my iPhone 15 Pro Max following updating to iOS 18. Everything seemed to be working fine, but now I am getting messages late. My friends with Androids are telling me that they're getting messages that say "message delivers when xxx is online" and I am getting the messages hours late.

Does anyone have any suggestions?

Thanks!

if you haven't already, I'd suggest restarting your phone to see if that helps. If not, try emailing CS Agent to have them confirm that PM supports RCS messaging.

You can contact them at this link,

@AS1992

I am on iOS 18 on RCS with a iPhone 14 Pro Max. Been using it for a day now an no issues.

I enabled RCS Messaging. Check if RCS is enabled by going to Settings>Apps>Messages>RCS Messaging and see if it is enabled.

You will need to contact customer service agent to fix your issue. Either via the following link:

If you are having a difficult time, then you can private message CSA:

It has been enabled the entire time, I even tried restarting my phone but it's still going in and out, very annoying!

So just to give an update, I found that RCS doesn’t work specifically on my workplace wifi. If my phone connects to the wifi for more than a few minutes, even if I turn off wifi, RCS won’t function until I actually leave my workplace and I’m assuming connect to another cell tower. Anyone have any suggestions of why this would happen?

Your employer probably blocks the port that RCS messages would flow though. My employers wifi blocks all sorts of things, including lottery sites, hence why I don't use their WiFi).

I wish I was able to pinpoint what it is that they're blocking that would cause this... I also find it odd that even when I turn off the Wifi, I cannot reconnect to RCS until I physically leave work, almost like it needs to connect to a new tower. It's very frustrating as the signal at my work for Public Mobile is not the best, very slow for data and calls drop.

HI @AS1992

with the Wifi issue, pretty sure it is a blocked on the Wifi level by ports or so

for the issue that you cannot use RCS even with Mobile at work, did you try reboot your phone at work and not turn on Wifi? next time when you go into your office, disable Wifi before you are there and use only mobile data and test RCS first

I contacted our IT department and will see what they say, not sure they're going to be helpful though. I did try rebooting my phone, and it didn't help. If I don't connect to the wifi at all and leave it off when I get to work, RCS continues to function (although my data speed is extremely slow due to the signal being weak). Very frustrating and I am hoping IT will be able to figure out what it is, just wanted to double check nothing on Public's side that would stop it from working.

HI @AS1992

if it works without connected to Wifi earlier, i think it might be the RCS designed to not re-try for some period of time after a failure to deliver (because blocked on Wifi )

for slow data, it is only in your office that data being slow? try 4G only and 5G only. See if it makes any difference. But it could be also a "dead" spot for Bell/Telus signal, could also be building materials related

The building I am in is made of concrete and steel and the tower for bell/telus is just slightly further than the rogers one... I have a work phone that runs off rogers and i get 3 bars of 5G on that one. I am hoping maybe it's a setting in iOS that will get fixed on a future update.

When I'm in my office tower I force my phone into 4G because I find it has a more consistently reliable connection than 5G. You've probably tried that already, but I thought I'd throw that out there just in case. 4G signal seems to penetrate obstacles more effectively.

My phone won't even connect to 5G when in the building, I get 1 bar of LTE. Funny enough, if I am further towards the centre of the building, it drops to 3G and I find that works better than the LTE speed wise.

hi @AS1992

if that is the case, you might want to change network mode to 3G only ..

It doesn't seem like Pubmobile is blocking RCS, it worked on my Google Pixel and usually works on my iphone 15, but funny enough today it's been very spotty, connecting to some people's chats then disconnecting after a short time. Those of you who always use RCS on iphone with public mobile, do you find it's always connected?

It's a shame, I'd love to use RCS more often but the excess battery draw just isn't worth it for the number of android users I text. Then add the extra data usage and the 1GB plan here doesn't get you very far especially with an iphone.

edit: I had to enable RCS to get a group chat to work again, one Android users messages in the group was not reaching me, but enabling RCS has fixed it.
