S25 ultra - preferred sim setting not available

Vitalsigns — Wed, 09 Apr 2025 16:50:52 GMT

I bought my direct from Samsung. I'm currently traveling and bought an esim to use for data. However in the sim manager the preferred sim choice setting is not there. I need to use sim1 for talk and text; esim for data. For the travel esim to work I have to turn on data while roaming. I'm concerned this will turn on the sim1 data roaming in addition. Any ideas or solutions

Good Day & Welcome to the Bell Community Forum.

The only way to avoiding roaming charges will be for you to remove your Bell Mobility SIM. As soon as you turn on data with the SIM in place, roaming is activated.

Roaming is only activated once your SIM card connects to a network outside of Canada. Therefore, if you remove your SIM card prior to arriving in the country and connecting to their network, roaming will not be activated. If your device is in Airplane mode, you can also connect to a Wi-Fi network & Bluetooth manually. You should have removed your SIM card prior to leaving Canada & going to Europe. In the event there is any mobile network connection active on the phone, once the SIM card is inserted and its able to connect, Roam Better is initiated.

Thank you for posting your question.

Take care.

Does bell firmware lock out the preferred sim settings in sim manager for android?

@Vitalsigns

It is very possible that it is baked in the sim card, but since your phone is from Samsung direct it has no carrier software. Certainly some apps are added via the sim activation but it doesn't touch firmware, but that doesn't mean that feature designs of how their service can be managed could prevent access to the sim management tool.

Only direct contact to a bell support level could speak directly.

Your direct question on how or can you use the sim management tools available to you, based upon my own research I cannot answer. The answer given tells you how to avoid roaming charges, but leaves the tool set question unanswered.

The basic information provided by Bell that I could find, but does not speak directly to your question about sim management tools on Samsung and my own pixel and I see the feature exists on many Android phones and on iPhones.

It is an interesting feature as if it works as designed when travelling we could keep access to our phone and text and dedicate our data usage to a travel esim if our use needs justify this over roaming or disconnecting from calls.

The one exclusionary clause I saw on Samsung and pixel was, if your carrier permits it. That is a question for Bell support directly. samsung support may be able to help to but may just send you back to Bell but worth a try.

Great question to learn how Bell interacts with what is a common feature on current phone versions.

Keep us updated to date.

Wish I could help more.

Enjoy you time out of country.

Hey Bruce

ive been in contact with bell. They are “ looking” into it. However it seems like it could be Samsung implementation of DSDS (dual sim dual standby) for the NA market. There are multiple complaints on Reddit of this option not being available in Canada and USA. Interesting that iPhones have it active. I’m going to walk into a mobile store and see their implementation

I found this online

As soon as we add a sim card (psim or esim) samsung checks the sim card provider from the CID manager and loads the appropriate CSC That CSC controls which options from the menu should be enabled and what the default options should be and gives the user the option to enable,disable, select/deselect.
This is the reason why the sim manager appears crippled on the US firmwares because the US CSC controls those settings.

I have dual sims on one of the iPhone 15 Pro phones in my house. There are zero operational issues and have been since Day 1. The movement from an older phone caused a small issue, quickly fixed by the provider after a visit to their store (not Bell). A store visit may be helpful.
