Melrose Labs operates SMSC simulators (aka SMPP server simulators) and Dedicated SMSC Simulators for use in the development and testing of SMS text messaging capabilities within applications. They simulate SMSCs (short message service centres) and SMPP SMS gateways, and simulate SMS message delivery. SMPP v3.3, SMPP v3.4 and SMPP v5 using TLS and non-TLS connections are supported.
Applications send SMS messages to mobiles by submitting messages to the SMSC Simulator service using SMPP. The SMSC simulators simulate the delivery of the messages, including the generation of delivery receipts back to the application. SMS messages from mobile numbers can also be submitted and delivered to the SMS application (see Simulate Inbound SMS to your Application).
The SMSC simulators enable you to send SMS messages from your application without messages being delivered to real mobile phones and therefore without any SMS delivery costs. Stress testing of your application can also be performed to show how your application behaves under load and various other scenarios tested before live operation and without affecting production SMSCs. The SMSC simulators can handle high rates of SMS and a large number of simultaneous connections from your application.

Why do you need a German phone number? Many countries let anyone have a phone number, with no proof of address or other identifying information. Just use one of those numbers instead. One example service is https://jmp.chat/ but there are many others. - Source: Hacker News / 4 months ago
Https://jmp.chat/ has been great for me, uses bandwidth behind the scenes and wraps the experience in a nice XMPP UX. Calls and texts work, only issues I've run into are the usual some services don't accept VOIP numbers, and group texts > 10 people I can receive but not send messages (bandwidth provider limitation AFAIK). Bonus is that their stack is all open source and since it's XMPP you can use whatever clients... - Source: Hacker News / 5 months ago
TLDR - I want to be able to take a bunch of sim cards, and use them to forward phones and SMS's to my actual phone. This would enable me to easily split my phone numbers up to multiple services without relying on third party hosts like jmp.chat or voip.ms. Another key tenant is that I want to avoid doing the calls and SMS's themselves over cellular - instead, wanting to rely on wifi-calling (VoWifi) - The point of... Source: 7 months ago
You might try https://jmp.chat. I'm very happy with them, I get SMS for everything I've tried(though I haven't tried everything/much). - Source: Hacker News / 10 months ago
Lol. Yeah, expect no privacy on the number. SMS isn't encrypted and its a pretty insecure and outdated technology nowadays, and if you're using it through Google Voice, Google will 100% have full access to your texts and calls through the number, which is obviously pretty horrible for privacy, especially with Google's terrible reputation and track record. If privacy is your concern, I'd recommend JMP. Its very... Source: 11 months ago
