What is a jmp.chat eSIM adapter?

I’ve been looking for eSIM / VOIP providers and came across this. I’ve heard about it here and there but haven’t looked into it until now.

First of all, is this a physical device? If so, it must be inserted into the SIM card slot? If it uses a SIM card slot, what’s the point of it being eSIM? The whole point of using eSIM is so that you don’t need a physical card.

Also, it seems to advertise that it uses the XMPP network using Jabber or WhatsApp or something. Basically, can you send and receive texts and calls to/from people who DON’T use any of these apps (say, they’re just using their local telecommunications provider)? If both parties need to use a specific app or protocol, I don’t see how this is any better than Signal.

Does the adapter go into your USB reader? Are there photos out there that show what the device looks like?

Does use of jmp.chat require one of these adapters?

Also, the app’s compatibility thing is saying

It is just a physical eSIM.

You can load any other eSIM onto it via the app and it works in any device as a normal physical SIM.

jmp.chat gives you a real phone number, but you interact with it using an XMPP client.

I already have eSIM on my phone, why do I need an external one?

Can you communicate with people who don’t use XMPP?

You don’t need an external one. You can load their eSIM onto your eSIM device regardless. Their physical eSIM is just available for compatibility with non-eSIM devices.

I see. They don’t really make a point about that.

But the issue I’m having now is the JMP SIM Manager app says “No JMP eSIM Adapter found on this device”. And the compatibility check shows that there was an error with ISD-R Channel Access. I have eSIM enabled on my device (but the slot isn’t being used).

You are overcomplicating this.

  • You do NOT need their SIM service to use their phone numbers.
  • You do NOT need their physical eSIM.
  • You can add their eSIM to any eSIM capable device by scanning a QR code like most other eSIM providers.
  • They offer their physical eSIM for devices that do NOT support eSIMs.
  • You do not need their SIM app. It is only for programming a non-JMP eSIM onto their physical eSIM.

How am I overcomplicating? I literally can’t use the service. I’m asking for help to fix the problem.

You must understand the JMP SIM / data only cell service is a completely separate product from their phone numbers.

Obviously I haven’t researched this enough. How do I actually obtain the number? The website gives me the option to get a Jabber ID from chatterboxtown (what the hell is that)?

Honestlg did nit know this was a thing this coukd be useful in combo with mifi routers. Which JMP had some PGPP kind of service for random unrelatable ismi combinjng that with a mifi router that can do random imei would be awesome and could save lives.

Wrote a guide on this, a while back - the recommended way to sign up is via android app. (You get snikket instance included with the service etc)

Heard gl inet was working on integrating eSim now,

pgpp shut service - had a chat they said their provider had some error

Which routers you prefer?

Physical eSim litterly breaks the security model lol

Elaborate please.

There is no direct difference between them.
Traditional eSIMs are just eUICC chips soldered to the logic board or virtualized in some trusted environment eg. TrustZone.
A physical eSIM is just one of those eUICC chips in traditional SIM card form factor.

Here is a common chip that can serve as an eUICC https://www.st.com/en/secure-mcus/st33g1m2.html

You could argue there is benefit to the lack of removability and the ability to automatically wipe the eSIM on device wipe, but otherwise there is no difference.

Where did you hear this?

It will be available on Mudi V2 this year. But it doesn’t matter because PGPP is dead.

Again how you know? Eventhough pgpp is dead this is interresting and could still be benefitial. One can manually change the IMEI and get a new esim for different situations (and by such get new IMSI)

Found something Will the Mudi GL-E750v2 have support for eSIM? - #3 by Dipin - Technical Support for Routers - GL.iNet

19

Yeah, this is where I got that from.

They’ve been working on that for a while now. I’ve been gunning for it for a while. I have the V1, sadly I couldn’t wait for the new version to be released. I’ll probably get the V2 eventually though.
