S24 ultra - Bell (physical SIM) apn settings keeps getting deleted after reboot

[Dual-eSIM-S24Ultra]

Device S24 Ultra

Physical SIM: Bell

eSIM: ROGERS 

No issue with my ROGERS eSIM, however my Bell SIM APN keeps disappearing. Impact is no data and MMS does not work. 

I have to manually configure Bell APN settings each time. 

Thought there was an issue with my (5+ year old) Bell SIM, so I replaced it with a new Bell SIM but that did not help.

I called both Samsung support and Bell Mobility tech support and they didn't help, just blaming each other, so we kept going in circles 🤦🏾

FYI, I previously had an unlocked international device - Note10+ Dual (physical) SIM and no issue. After upgrading recently (about 2 months) to S24 Ultra, no issues even after updating to the latest Samsung software update, until recently these past two weeks.....

Does anyone have a solution for this?

On my fold 4 I can use 2 esim. So I think you can do the same with S24 Ultra

[RedDogRabbit]

I think that you can store more than one eSIM, but I don't think that you can use more than one at the same time. 

[Parseneault76]

Ok. Maybe you're correct. I can see on internet that you can store 2 esim but you need to use one at a time.

Alright, so fingers crossed, after wiping cache from boot recovery mode - I did this 3 times lol just thinking that might make a difference, well it's been a few hours and I have restarted my phone and fortunately my Bell APN did not disappear. Yay!

I think the issue is intermittent, and the true test will be if the APN does not randomly get deleted some time later this week or anytime in the future. I don't mind if I have to manually add the APN once a year lol but certainly not once a week. Anyway, fingers crossed.

If the issue happens again, then I'll try moving to two eSiMs (Bell as my primary eSIM, and ROGERS as my 2nd eSIM)

Re the above comments about two eSIMs, yes this feature/capability is supported on S24 Ultra. While both are eSIMs or SIMS are active, technically only one can be used at a time, just like if you had 2 physical SIMs (like my previous Note10+ international device) or like now I have 1 physical SIM (Bell) and 1 eSIM (ROGERS).

For calls I just use call-forward feature to have all my eSIM (ROGERS) calls forwarded to SIM (Bell), so I never miss a call on either SIM/eSIM. One key point or limitation to remember is when I'm on a call (which will always be on my primary SIM(Bell) since my ROGERS calls are always forwarded), well during the call, the eSIM (ROGERS) becomes inactive, so unable to receive or send any eSIM(ROGERS) SMS/MMS, and unable to use eSIM(ROGERS) data. So if someone sends me a SMS/MMS on my eSIM(ROGERS), while I'm on a call SIM(Bell), then that SMS/MMS on eSIM(ROGERS)will have a delay in getting received/delivered until the call on SIM(Bell) ends. This is just a typicsl limitation of all dual SIMs devices, so that aligns with the comments above that you can only use 1 SIM at a time, whether it's a physical SIM or eSIM.

For SMS/MMS, I have a choice to use either SIM(Bell) / eSIM(ROGERS) depending on if it's a personal or business contact. There is also the option to set default SIM/eSIM for each contact or just in general for any calls or text msgs within SIM Card Manager feature. Finally, for internet, again, I have the flexibility of choice to use WIFI, or SIM(Bell) data or eSIM(ROGERS) data.

Day 2, so far so good 🤞🏽

Unfortunately unsuccessful. My Bell APN got disappeared again some time earlier today. This is so frustrating!!!

@Helenna - What do you suggest is the next step? Please note I called both Samsung technical support and Bell Mobiliry technical support....and we keep going in circles as they keep blaming each other.🤦🏽‍♂️

Try to reset mobile network settings. Carriers do updates and if features stop working then this should be the first step.

[Dual-eSIM-S24Ultra]

@slinkyaroo - thanks. Quick clarification, resetting mobile network settings was actually the first step I tried. Unfortunately this did not work and ai actually tried a few times but unsuccessful

I am facing a network connectivity issue in Canada after the last update. Network disconnects from Telus within a few seconds after restart and option to select Mobile Network type can not be changed from native setting.

My physical sim from India uses Telus 4G( no LTE or 5G supported), and Fido uses 4G LTE.

To fix it, downloaded an external app to force different network types and it is working fine now.
