And I was able to receive a picture. The first attempt failed. I hit the red download button and got it on the second try. I might spend some time trying to figure it out, but am okay with it for now. (maybe because I have an Internet SPN and an MMS APN? Maybe because I am connected to both wifi and cellular with an LTE connection?)

I compared APN settings to my Android phone that is also on Mint Mobile. This worked for me, and let me send photos.
So, here is what worked for me:
Name: ultra (all lower case)
APN: wholesale (all lower case)
MMSC: http://wholesale.mmsmvno.com/mms/wapenc
Proxy: leave blank
Proxy port: leave blank
User name: leave blank
Password: leave blank

On my tests, the picture did not go through the first time, it failed. I hit the red failed icon to try again - and it worked on the second try. Not sure why. But I'll take it.

I asked my son to try sending me a picture. Once he does, I'll know if receiving pics works. But I'm calling it resolved.

I forgot to add that wifi is enabled and my phone goes between L and 5g depending on where I am in the house. But I did not turn wifi off.

I'm not on Telegram, but probably should be. Thanks for the head's up.

So, I thought and thought and thought. And decided I am missing something extremely obvious. I have two Mint numbers for me - one for my Android phone, one for Ubuntu Touch. And I have a 3rd for my son's iPhone. And a fourth for my wife's iPhone. They are all on Mint. MMS works on all of them except my UT phone. Maybe I ought to just look at the APN settings on one of the working phones and compare it to mine.

So, here is what worked for me:
Name: ultra (all lower case)
APN: wholesale (all lower case)
MMSC: http://wholesale.mmsmvno.com/mms/wapenc
Proxy: leave blank
Proxy port: leave blank
User name: leave blank
Password: leave blank

On my tests, the picture did not go through the first time, it failed. I hit the red failed icon to try again - and it worked on the second try. Not sure why. But I'll take it.

@gpatel-fr I can't receive pictures my son sends to me. I can not send pictures taken with my UT phone. Neither works.

I have a OnePlus N10 Nord 5G running 24.04. It's working pretty well, but I can't seem to get MMS working. I can't send pictures to my son (gotta share the home made sourdough bread pictures and photos of birds at the feeder!).

This is what Mint Mobile site says to use:
APN Settings

Name – Mint
APN – Wholesale
Proxy – (leave blank)
Port – (leave blank)
Username – (leave blank) 
Password – (leave blank)
Server – (leave blank)
MMSC – http://wholesale.mmsmvno.com/mms/wapenc
Multimedia Message Proxy – (leave blank)
Multimedia Message Port – 8080
MCC – (do not change default values)
MNC – (do not change default values)
Authentication Type – (leave blank)
APN Type – default,supl,mms,ia
APN Protocol – IPv4/IPv6
APN Roaming Protocol – IPv4/IPv6
MVNO type: GID
MVNO value: 756D

I don't see an option in the GUI for a lot of these settings, but I did set Name to Mint, APN to Wholesale, MMSC to http://wholesale.mmsmvno.com/mms/wapenc. I left proxy and proxy port blank.

When I do this, my phone takes forever to start up and I have to force a boot (hitting sound up/sound down/power at the same time and holding for 10 to 20 seconds).

Anyway, sending pictures is not working, and a simple boot fails.

Thanks! I turned off RCS in Google for my sim. I also tried turning off wifi. And blanked out the proxy port setting. Still no luck sending a picture. I'll open a second topic asking for any Mint Mobile users to share their APN settings for MMS, just in case I might need to go beyond the GUI settings and edit via terminal. But for now I swapped sims again. Moved my primary back to my Pixel 6a running android and my secondary to my Ubuntu Touch phone.

But the phone did pretty close to great using it as a primary yesterday. No problem sending and receiving calls while out and about. No problem sending and received texts (without images) and forwarding my purchases to my wife as we track what was spent and where it was spent). No problem selecting a Podcast and playing while doing errands. Currently enjoying The Guardian - but lots of choices. uNav worked just fine. I saw that when I clicked on my favorited home address, GPS kicks in much more quickly. No problem installing uTorch to use my phone as a flashlight at night. Web Browser worked just fine, but some sites gave me warnings about it being unsupported. It just worked anyway.And KeePassXC worked like it should, no issues. I can't edit entries, but I normally do that on my desktop, then copy the database out.

So - keeping the phone. Will watch for MMS working. As I did miss a text from my son where he sent a picture of an award he earned at work, and my response was to please e-mail photos. That was not the right response - once I saw his text on my wife's phone (he sent it to both of us), I properly congratulated him.

Anyway, will watch for MMS and will try to tweak settings. But the phone was very close to doing what I needed it to do.

@rocket2nfinity the sim was in an android phone. I'm not sure how to turn RCS off, but will look it up. Wifi is on. I don't get a good signal in my home, so I call over wifi, unless I'm out.

For MMS I used these settings:
Name: Mint
APN: Wholesale
MMSC: http://wholesale.mmsmvno.com/mms/wapenc
Proxy: left blank
Proxy port: 8080 (not sure if this should be blank)
User name and password are blank

I'm not sure how I should configure nternet, or just leave it alone.

Sending a picture fails.

I have a OnePlus 10 Nord on Mint Mobile. I can send and receive regular text-based messages (just regular text). When my wife and son send images, I get a "Could not fetch the MMS message. Maybe the MMS settings are incorrect..."

Is there anything I need to tweak to be able to view pictures, screenshots, gifs, jpegs, ... when receiving text messages?

I am on Mint Mobile in the US.

you were right
port 587
encryption: starttls
authentication: plain

it's working!

(now to set up my fastmail account)

I tried 587 / STARTTLS / PLAIN with no love. I saw that my account was not set up properly, so copied how I have it set up in Thunderbird. No Dekko2 does not crash when I try to send mail. I tried 465 / Force SSL/TLS / LOGIN again.

I must not have my folders configured correctly. When I send a mail from Dekko2 it hits my Outgoing folder, then pops into Drafts. I looked at my Thunderbird application on my desktop and can see the email I sent from my phone sitting in Drafts on my desktop in Thunderbird.

So - the email is going out. But instead of going into Sent and heading off to the right person, it pops into Drafts on both my phone and Thunderbird (so it is in Drafts on my GMail account).

I notice that in Dekko2 Copies and Folders - Outbox Folder is blank. Sent folder is [Gmail]/Sent Mail - and that does put it in my Sent Mail folder on my GMail account - but also puts it in Drafts and it never hits the recipient.

How are your folders set up?

I am running a OnePlus 10 Nord on 24.04-1 (2026-01-17). Dekko 2 works fine for incoming GMail. I get the mail in my inbox. I can see all my IMAP folders. I can read e-mail. However, when I go to reply, it crashes immediately.

My outgoing server setting are - hostname: smtp.gmail.com, Port 465, Username (my google user name that works for IMAP), Password is my App password that works for IMAP. Encryption selection is Force Encryption (SSL/TLS), Authentication is LOGIN. Authenticate from Server Capabilities is turned off. Allow untrusted certificates is turned off.

Any recommendations for configuring outbound server for GMail?

@rocket2nfinity uNav worked great last trip. I just clicked on my Home location and GPS kicked in very quickly. I'll need to check your method as well. I was out and hadn't researched, so just tapped things. Anyway, PodCat worked just fine for playing Good Hang by Amy Poehler while uNav gave me directions home. And dekko did great for email notifications.

I decided to forward my primary mobile number to my Ubuntu Touch phone while running errands today. Forwarded calls, powered up my phone. Must have hit something while transporting the phone before it was fully booted, as I got stuck in a boot loop. I put it away while I went about my errands. Researched when I got home, and all it took was hitting power and sound up at the same time.

Oh well. Phone is u and working. I can forward my calls. I don't see an option to forward SMS messages. I'll research that a little more, as I'd rather not swap sims based on what physical phone I want to use as primary.

My granddaughter is over for a couple days visit, and we decided to go out and play disc golf. I thought it would be a god idea for her to tuck a phone in her pocket and practice calling her dad, her mom, and me.

We practiced hitting the power button, sliding to the left and to the right, finding the contacts icon and finding her parents and me. Got great cell coverage in NWATL area.

I think I need to explore a few of the games next. But Ubuntu Touch on a OnePlus Nord N10 on the Mint network is 8 year old granddaughter approved. Well, we'll need to check messaging next. Granddaughter texts are very emoticon heavy. We haven't checked that out yet.

I ran Ubuntu Touch a LONG time ago, on a Nexus 5. I wanted to see where things stood, but didn't feel confident in being able to unlock the bootloader and install UT, so I bought a pre-loaded OnePlus Nord N10 off eBay. I wanted a second cell number, so I ordered a line off Mint that is limited to 5 Gigs of data a month. I just wanted an inexpensive line.

So, I wasn't sure how to activate the physical sim, as I did not load the Mint app on my phone. I poked around, then figured I'd just call my home line from the new cell phone to see if I got dial tone. And it immediately went to Mint Mobile. They activated the line no problem! I didn't need to worry activating my sim at all.

I connected it to home wifi with no trouble at all. I was able to make and receive calls and text. I use KeePassXC on my Ubuntu desktop, Win11 laptop, and KeePass2Android on my Pixel 6a. I asked the forum, and installed KeePassRX. I wasn't sure how to get my database file over, but ended up sftp'ing it off my Raspberry PI. You can't add new entries on KeePassRX (if I read right), but that shouldn't be a major issue.

I tested logging in to a few favorite places with no issue.

I wasn't sure about email. I read about the Dekko2 client, but also saw that it has privileges to every file on the phone. I wasn't sure about that, but decided to give it a try. It works just fine with GMail. I just had to configure an app password. I get notifications when I receive an email.

I had to run errands today, so left my Pixel 6a at home and took the OnePlus. I decided to try UNav. It took a long time to get a GPS signal, but eventually picked it up and it mapped my route. I then tried to put in my home address, but the map didn't recognize it. When I got home, I just favorited my driveway and labelled it Home.

While out, I checked the phone in a Kroger parking lot. The phone showed 5G. I was pretty happy with that.

I'll poke around for a podcast app next. When driving I typically use a navigation app and stream podcasts.Hopefully I can download the podcasts first, while on wifi - then stream them when out driving.

@Vlad-Nirky Thanks - I'll mess around with that later. I do have a cron job rsynching keepass and gnucash files from my Ubuntu desktop to my Raspberry Pi. My Windows 11 laptop runs Ubuntu in WSL. I use rsynch to grab current keepass and gnucash files off the pi. I am rusty on setting up keys, so will need to reread some documentation. But that would solve keepass currency issues pretty quickly.

Replying to myself. Copy works just fine with a long pres.Sorry for asking ignorant questions.

Thanks for the info! I installed KeePassRX. I copied over my database file using sftp. Ignorant question - I see how I can copy the url, userid, password in KeePassRX. How do I paste it when I am in the web browser? I'm used to ctrl/c, ctrl/v or in Android just a long press. I opened up a browser but had no idea how to paste the url in.

I run KeePassXC on my Ubuntu desktop and Win11 laptop, and KeePass2Android on my Pixel 6a. Is there a version of KeePass for Ubuntu Touch? And how would I install it?

I keep a copy of my database on a Raspberry Pi set up for file sharing (Samba - but I could do different methods if needed). Does Ubuntu Touch support Samba CIFS client on the local network? Or would I need to grab the keepass database using a different method?

Sorry for very basic questions. I ran UT on a Nexus 5 a LONG time ago, and thought I'd try again by cheating and buying a phone with UT pre-installed. At this point I really only can turn it on and connect it to my wireless network - I am very out of practice.

Thanks! I posted a little blurb on the Nexus 5 Ubuntu Touch G+ group. I also installed Stable, RC-Proposed and Devel-Proposed on my N5. Very slick! I used it as a mini-tablet for a bit, then installed Stable and swapped my SIM out of my daily driver Cyanogenmod phone to my N5. Will use the N5 as a daily driver for a bit.

I would like to figure out the Bluez integration, but think I'll just use the N5 for a while before swapping the SIM card back out and using the N5 for development again.
