Another report: I recently was in Italy for holidays and bought an eSIM (from surfroam) as addition to my standard swiss SIM (M-Budget aka Swissom Network) that didn’t have enough data included (at least not for roaming).
I suffered heavily from both SIMs (the SIM and the eSIM) having exclamation marks in both indicators in the top status line. As I was travelling a bit off the large cities, I blamed this to the bad connectivity available in rural italy. However, most of my travel mates had acceptable connectivity, at least it was much better than mine.
Being back in Switzerland the problem persisted. As I never had such issues before having a 2nd SIM, I started to investigate and this brought me to this thread (which is still unsolved as far as I can see).
The only solution that worked for me was to disable one of the two SIMs and restart the phone and wait a few minutes until the still active SIM established a connection.
As this makes me unreachable for standard telephone calls and SMS messages, this is just a emergency workaround. And makes the FP4 basically unusable with two SIMs (at the same time).
Please note that is not a general problem: I for instance am using two SIMs (French and German) for a couple years (tired of lugging two phones around), and didn’t notice any connectivity or other issues.
Now this is not just another “too bad for you, I’m fine” post, my point is that the issue is unfortunately very complicated, because we don’t have a consistent and universal situation but a slew of slightly different issues all affecting dual SIM use. Is everything due to one and the same FP4 problem? Are there several distinct problems somehow affecting dual SIM use? Whatever it is, we most likely won’t ever know.
Hi, my wife and I have been seeing the same of at least a a similar issue for some months now: We both have FP4s (1 x 128 GB, 1 x 256 GB; on Android 13) and the same provider (1&1, Germany, physical SIM, no second SIM). Occasionally, we lose both mobile data the ability to start or receive phone calls). After a few seconds to minutes, it works again.
It is not happening at the same time on the two devices. I have observed it with both phone laying side by side: One shows a normal connection, the others show the infamous exclamation mark. At some point, both work and shortly after the first loses connection.
Before this issue appeared first a few months ago, both phones have been working fine since 2022, respectively early 2023. Until today, I blamed it on our provider, but after reading this thread and a few other posts, I think it is probably a fairphone issue.
Good morning
My SIMs seem to be working now (using them at the same time). It noticed it last week and it’s been working well since. Has anyone else noticed this as well?
Still no luck with my phone… I’m trying to change (another) provider, even with the lowest expectations.
This is my last chance before having to change my phone
So I extensively did test this solution while moving and it turns out, turning 5G off is for me the solution and I never lost connection again anywhere
After the update to Android 15 the issue seems to have resolved or at least considerably reduced. The overnight battery drain has more than halved and I did notice the exclamation mark only once since then but it was gone shortly afterwards without any intervention.
I experienced the same! Since the update I didn’t have the issue anymore and can finally have both the SIM’s active and still have connection on both of them. Very happy this has been resolved at last. Immediately ordered a new battery, as I was postponing that until the issue would be resolved (I was in the process of selecting an other, new phone, due to this problem not being addressed properly; but no need for a new phone now anymore, a new battery will be sufficient).
Hopefully this solved the issue for all of us in this thread.
