Any client that can do voice calls will work with JMP.chat. As a user generally it's not useful to think about XMPP or protocol extensions, this is an implementation detail if you're building a library or SDK. We consider Cheogram Android to be a first-party app and all Snikket branded apps to be pretty close, everything else is a third-party app with the uncertainty that entails, but basic functions like text messages and calls are standard enough to pretty much always work.
If you try the sign up process you will see what payment methods are supported. Namely: credit card, bitcoin, payment by mail, or (in Canada) interac e-transfer.
If you contact support you can get an address for ETH or XMR as well for signup, these are not fully automated yet.
Yes. It's automated for top ups but not for signup yet, but you can contact support https://jmp.chat/faq#support to get an XMR address for signup purposes.
would I still be able to use the actual phone to dial 911 if necessary?
Carriers in USA are required by law to complete 911 calls even if you are not a customer and have no SIM card at all. So yes.
I saw something about an ESIM adapter that’s a regular SIM card that can have multiple ESIM profiles on it. Why can’t I just buy this directly?
I wrote some thoughts about this at https://blog.jmp.chat/b/2022-sms-account-verification
If verification texts are important to you you can also asking JMP support about getting a "Premium+" number, which is managed by a partner who has back channels to yell at many verification providers if they reject a number.
You can't forward SMS due to how the protocol works, but calls you can forward using the "configure calls" command with the bot. Set the URI to tel:+15551234567
I barely even noticed they got replaced. They never got to have any story involvement or character development, just like most of the rest of the bridge crew in Discovery.
I really found the coda/epilogue to be distracting. The end of the main story ended in a good place, with Burnham and Booker heading off on their next adventure. And then suddenly we're getting this long drawn-out "and then later after many adventures they... did something useless we can't explain but at least they saw their old friends again the end" just really took the wind out of it.
You mean you'll only see content from people you follow and only people who follow you will see you content? Sounds like working as intended the way things were meant to be.
