Public Mobile APM on adroid 14

[cividan]

Hi, I just bought a brand new OnePlus 12r with oxygen os 14 (android 14) but the MMS message doesn't work, I had this problem on my old OnePlus 7t earlier this year and it was stated that if i had a up to date phone the APN would have been published correctly well guess what they're not. That's a big frustration and add to that the fact that putting the setting I had on my previous phone doesn't work. I tried 2 different messaging application and they both react the same way MMS wont go thru.

Here is my current settings:

Name: Mobile Internet

APN: sp.mb.com

proxy: not defined

port: not defined

username: not define

password: not define

server: not define

MMSC: http://aliasredirect.net/proxy/mb/mmsc

proxy MMS: 74.49.0.18

MMS port: 8799

MCC: 302

MNC: 220

Auth: not define

APN Type: default,mms,agps,spl,fota,hipri

APN protocol: ipv4

roaming APN: ipv4

Network: unspecified

MVNO type: GID

MVNO value: 4D4F

Can anyone tell me what's wrong and how I can finally fix that or do I simply need to change for a new reliable service provider.

Hi, I created a new access point called public mobile with these settings:

APN: SP.MB.COM       
Proxy:
Port:
Username: <blank>
Password: <blank>
Server:
MMSC: http://aliasredirect.net/proxy/mb/mmsc

MMS Port: 8799
MCC: 302
MNC: 220
Authentication Type: Not Set
APN Type: default,supl,mms
         (from my reading no other APN type should exist here, supl is probably also even not needed)
                Reference: https://tamingthedroid.com/apn-type

APN protocol: IPv4
APN roaming protocol: IPv4
APN enable/disable: APN enabled
                or  Turn APN on/off APN turned on

With OnePlus, there might be a bit more work than simply updating.  Many confirmed that you need to delete the current APN profile first.  Then Add new profile and add according to this, please note case-sensitive and do not add extra spaces.  Remember to save the new APN and then reboot the phone before you try

APN: sp.mb.com
         (or try all upper case SP.MB.COM)
