iPhone sending SMS instead of iMessage without internet connection

[Astrohunter]

Hi,

My brother bought an iPhone and he has often poor internet connection.
Quite often when I send a message it will try to send it as SMS instead of iMessage.

Could it be related to him having poor connection?
I have never seen this issue before.

Cheers

Yes, poor internet connection can cause messages to be sent as SMS instead of iMessage, as iMessage requires a stable internet connection. When the iPhone detects that iMessage cannot be delivered, it defaults to sending the message as an SMS.

Encourage your brother to check his internet connection and possibly troubleshoot any connectivity issues to improve his messaging experience.

That's a big bummer then compared to apps like Signal, Telegram etc.
Luckily I have set a spend limit so Vodafone keeps sending me SMSs saying that I can't send the sms because of limit spend.

He lives in a small village in Switzerland so not much he can do.

I thought iMessage will wait until there is connection or something.

iMessage does indeed attempt to send messages when there's poor internet, but if it fails to send after a certain period, it defaults to sending as an SMS if the "Send as SMS" option is enabled in the iPhone's settings.

That's very interesting. In America it's normal to have unlimited SMS which allows your iMessages to get sent quickly and consistently even if the internet is poor, which Telegram and other apps may be unable to. I've never thought of that as a bad thing.

I'm in UK and he is in Switzerland, so that's the issue.

That wouldn't matter here in Canada, our plans generally have unlimited worldwide SMS. Although we do have very expensive/stingy phone plans so you're not really missing out.

You might try enabling “Wi-Fi assist” in the cellular settings if it’s not enabled. That will cause the phone to use cellular data for certain things if the Wi-Fi connection is poor.

No problem. You can uncheck the "Send as SMS" in the Message settings. This means that iOS will not automatically send an SMS, only if the iMessage fails and you click on the message to "resend" or "send as SMS".

SMS and iMessage are two different things. An unlimited SMS plan isn't going to help send an iMessage if you have no internet connection.

Does he have Internet at home? Or does this just happen when he's outside in that small village?

I'm also from Switzerland and there's always one of the networks that work, everywhere, with very few exceptions. Maybe he could look for a different mobile operator?

But yes, what others said is correct: just disable the "send as SMS" in your iPhone settings, so it won't do that. Or use some other app, like Telegram, Signal, etc.

Also from Switzerland (just outside Zurich) here. It would be interesting to learn about your brother's network carrier and rough locations.

Yes I was simplifying it. Your iMessage can be automatically converted and sent as SMS if there's no internet connection when the setting is enabled.

In your phone settings under messages you can uncheck "Send as SMS" and it will try to stick to iMessage for iMessage contacts. You probably have it checked so it times out and sends as SMS automatically.

He is in Leukerbad.

But then if I sent a message to Android user will it send the message at all?

Leukerbad and Lebara network, latest Iphone.

It will still send as SMS to Android users. That setting only switches off the fallback to SMS if for any reason (like bad network coverage) iMessage is not available.

Also, Lebara is on Sunrise network, and I usually have good reception with Sunrise in Leukerbad (although I'm not there often). I suggest he gets a fixed/landline Internet connection to use at home, and only uses his cellular data when outside. This way it should always work.

So if i disable it, it will use imessage once he gets internet connection?

I am not sure if it will automatically retry once it gets Internet connection, or if it will fail with an error, then he needs to click on it again to retry. It's hard for me to simulate these conditions, so you need to do some tests. Maybe someone else knows.

My LTE plan is fairly light so I've on occasion got charged for sending a MMS when it didn't properly go through iMessage, instead sent via SMS. So now I tend to check first if my "send arrow" turns blue from the get go.
