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.

I know this was a scam, but I spooked them (or broke the bot?) before I heard their plan. I did a reverse image search, and I found nothing. I looked at the metadata on the image, but I saw nothing useful. I looked up the number and found out it was a virtual number from bandwidth.com. I didn't know what to do after that, so I just reported the number to bandwidth. Source: 5 months ago
I wanted to add a secondary provider though with Direct Routing for fail over but was looking for recommendations. I'm in Canada so prefer someone with a Canadian POP but not mandatory. I also prefer self-signup when possible, similar to Telnyx, Flowroute etc. I was checking bandwidth.com as I see they do this but it doesn't let you sign up and wants you to contact sales. That's fine and I was planning on... Source: about 1 year ago
You can pop your area code and prefix in the link below and see what providers do have a presence. Obviously, Sprint/T-Mobile will be one of them but if you don't see bandwidth.com then you're out of luck and there are no workarounds. Source: over 1 year ago
Your provider should be able to provide a short code (e.g. '933' if using bandwidth.com) that will read out the e911 information for the number calling. Source: over 1 year ago
While I think you have your answer, another way to validate a number is to use https://freecarrierlookup.com/ and check the phone number. From that you can often tell if it is a "web only" number that a scammer outside the US would use. For example, it might belong to bandwidth.com or google voice. If it does belong to Bandwidth.com you can report it to them, and they are really fast at cancelling scammers. Source: over 1 year ago
