Unlocked Samsung Galaxy S25+ sending MMS messages delayed or failed at sending

[WiSeIVIaN]

I have an unlocked S25 Ultra purchased directly from Samsung. I am on Verizon and use eSim. And I use Textra. I have had no issues, I'm glad to say. Not sure it's of any help to you but for comparison, here are screenshots from my APN screen.

Did all 3 grabs attach? I'm only seeing 1 pic but the links for the other 2 are there.

Thank you, I'm only seeing the middle screenshot for some reason. *EDIT*

That's relevant but irrelevant. Verizon's SIM be it physical or digital should be telling jr phone what to provision. What phones did you come from?

One was previously a s23 ultra (purchased from verizon) and other was a s24 (purchased from verizon). Same physical sims being used in the s23/s24 and the new s25+'s. Even though now (as of today after months of issues) the s25+'s are on eSim which a verizon store tried to do to help.

Not sure what "ninja'd posted" means??

I have manually changed nothing. But it's all working fine for me.

To clarify, are you doing group text messages (MMS) and sending pics/gifs on them?

If I only did 1v1 messages (SMS) and RCS, I would not notice the issue.

Hmm.. Does OP use any VPN or ad guards?

No VPN or ad guards on either phone, nope.

MMSC is still blank, I agree if I could somehow get this to enter the address, it seems like it'd solve my problem...

Thanks so much everyone who is replying!

You can reset the APN in the upper right 3 dots see if that helps

Thank you, my screenshot #1 and screenshot #2 are exactly the same as yours. I was mistaken about the bearer, mine matches yours perfectly!

if I click upper 3 dots it says "discard" which doesn't do anything. All APN settings are grayed out under the verizon sim, I cannot +add, or edit anything.

It's worth noting that I just successfully activated a mint mobile trial sim. Mint mobile seemed to populate with correct APN including their own MMSC. I am able to send MMS messages and gifs via mint mobile sim with zero delay or issue.

Still unable to edit the Verizon APN or solve any issues. Has to be a MMSC issue...right? Just no idea how to change. I tried MyTechSuite and some other discontinued samsung APN forcer, but it seems like both are patched on android 15 because they don't work or edit the verizon APN.

Thanks, confirmed the same on all 3 screenshots. So just to confirm, you're able to do a group non-RCS text message and send gifs or screenshots with no send delay?

I'm having no issues at all using Textra. Group messaging, sending/receiving pix or links, 1 to 1 texting, all is good with the way my phone is set up as shown on the APN screens.

I had to go to a Verizon store & they set up the eSim. I tried to do it myself on-line and Verizon flagged it and totally deactivated my service as fradulent activity!

Correct. No delays and no problems at all.

Then I'm leaning on a Verizon issue, maybe stop in a Verizon store have a person look at it , Verizon does some stupid things on unlocked devices which they shouldn't, not being able to add a APN or reset are a few

Unfortunately I went to a Verizon store today and their only solution was to switch to esim, nothing further.

Samsung wants me to take to ubreakifix, thinks there is any way they can help me?

Verizon technical support pushed me off to Samsung and says they've done all they can.

You can try using Odin going from unlocked firmware to a carrier and see if you have better luck

No. They are physical repairs. Verizon is doing what Verizon does, make it not their problem. Male sure it's an actual Verizon store. Authorized and Retail stores look very similar. Go to a different store.

Not very beginner friendly approach (not your advice, the process) on a warrantied device. You also can no longer dirty flash between them, you will brick. You must wipe the phone now.

I'm not on the s25 if it resets , haven't flash it yet, but from others that have seems like went smoothly, but it shouldn't brick these are stock official Samsung firmwares

Thread 'Odin/Seamless Updates '

I don't know what's going to happen with Odin for the s25 line up with seamless updates now , might have a different Flash tool or change something in Odin but be interesting to hear anything going forward.

Thank you for your help today. Odin definitely looks like a solution, but per the other commentor i'd be a bit out of my depth and at risk of bricking

Thank you. I will go to a corporate store again tomorrow and try my best. So do Verizon Corp stores have the ability to force APN changes somehow?
