Unable to download MMS on wifi without international roaming (S9, T-Mobile)

Hi all,

I have a stock (unrooted) S9 on T-Mobile and use Google Messages and/or Samsung Messages (the built-in app.)

I travel internationally and recently started receiving "gentle" reminders from T-Mobile that "roaming benefits are not intended for extended use abroad." You know, "Sprint will be better with T-Mobile", blah blah blah.

Anyway, I am usually on wifi so I disabled roaming. No issues except now I am unable to download MMS messages (text or photos) in groups I created UNLESS I enable roaming back on.

This is happening with both Google Messages and Samsung Messages apps.

Is there some setting or configuration that I am missing or is it that wifi is not enough and mobile data/roaming is required?

My concern, of course, is that T-Mobile will press the issue if this scenario continues.

Thanks in advance

Unfortunately MMS exchanges between different carriers cannot always work over WiFi, some have to take place over cellular connectivity only. In those situations, you do need to have mobile data enabled (roaming is not a requirement).

Welcome to AC!

This TMobile branded S9 ?

Try resetting network in setting

The MMS in question come from the same carrier. I am abroad, however, so maybe I am 'technically' on a different carrier?

Welcome to Android Central! How long are you staying abroad each time?
Thank you so much. My stays vary. Sometimes a few hours (jump the wall and back, you know), sometimes a couple of weeks. Mostly Mexico and Canada.

Thank you! T-Mobile SIM card, so I think the answer is yes. I reset the settings multiple times

I wish. I never switched it off before and would keep it on but T-Mobile started nagging about extended roaming abroad. I thought I can turn it on when there's a rare urgent need, like navigation or similar. But now I am unable to send or receive any MMS (photos or even group texts as MMS) without constantly toggling the switch.

Do you have a high tier plan with them?

If you're not staying more than a couple weeks at a time, you might want to give Google Fi a try. One of their strengths is ease of use internationally. They also make it clear that they don't allow prolonged use abroad, but they might be more flexible than T-Mobile.

I have TMobile unlimited everything think thats Magneta plan which covers Canada and Mexico
The plan is a conversion of the Sprint Unlimited plan. It covered Mexico -and still does- but all plans have a 50/50 clause. I guess Sprint just never enforced it in my case.

I appreciate the suggestion and maybe.

I was just hoping there was a way to continue to receive MMS and fully use my phone while roaming is turned off and I am on wifi.
