I would like to report that I have tried RedTeaGo on a new Mudi7, esim carrier which is listed as working with Mudi7 and other physical esims (position 5 in your list), and after speaking several times with the customer support and then allowing them to remotely-test the situation themselves, it DOESN’T work, unfortunately.
I notified the support team about this inconsistency. Following this, it becomes rather hard and unreliable to use esims, I am not sure whether we can still trust all operators listed as working, and if all we can do is buy cheap minimal esim to test before buying a real one, and having a very minimal list of operators they will probably not be the cheapest among the whole list available, for example, on esimdb or other marketplaces like mobimatter or airalo….
In this context, I would like to ask, as I have not seen this info anywhere, does any PHYSICAL SIM (I mean SIM, not physical eSIM), work? All of them, or just those from actual carriers? Do virtual operators work, too?
This could help with usecases, although the real help is to make it usable with any eSim…
Thank you and congratulations on such a great device. Would be great if you could also expand this eSim functionality to more/all operators.
Nearly all SIMs should work as long as the carrier uses frequencies the modem can work with.
It depends on contracts, mostly. But the Mudi itself is almost the same as a smartphone.
However, there are issues when you switch between continents. So something that works in the US might not work in Europe or vice-versa. But this is the same with some phones as well.
Yes, makes sense. I operate in Europe, which has rather standard bands (e.g. 1/3/7/20 for LTE etc) and as far as I know, most Africa / ME / APAC except Japan and China are quite the same, while US / Americas have certain overlapping bands but typically use different ones.
My problem is that the first eSIM I tried didn’t work, albeit it was on the list, listed as working. Also, the first physical SIM from a local national operator failed (I will report this to technical support). And there is uncertainty towards random eSIMs not working, which makes it difficult to go around shop for cheaper ones and adds the time consuming tiny-data-plan-test-eSIM purchase.
Otherwise, especially if the modem problems can be fixed, the Mudi7 is definitely one of the best devices I’ve seen.
I tried a sim from a national operator (226 - 10). It has a phone number as well, data allowance on a subscription, etc. Tried on SIM1, on SIM2, tried with all APNs I could find (though the first one worked on every other device). Tried 4G/5G, IPV4 or both, nothing worked. Same “cannot connect” error. I’ve reported this along with logs to the technical support.
The 4G and 5G networks were visible. The SIM would even receive SMS! but still won’t connect to data.
More and more I believe your modem (or its firmware) is the problem. There is even an offline html instruction page for updating the modem firmware, but there is no such update check available in Updates, only the general Mudi7 firmware (for which I am using the latest, 4.8.3. There are no betas on the main firmware download website)
