I operate a telephony service (perhaps similar to the one you parked your number at) and we do thousands of ports a year from our service to major carriers. Porting is such a backwards pre-internet system and things go wrong all the time unfortunately.

My guess is that the port went through but US Mobile has lost it in their system.

One of the biggest issues I see is when porting from a VoIP service to a carrier. The carrier doesn't always know what to do since it is slightly outside normal; the majority of their customers are moving between major carriers. But now your number has been classified as a "wireline" (VoIP) number and US Mobile is probably confused.

Honestly, I bet it magically arrives at US Mobile after a bit of time. But if you can't wait, I'd engage the VoIP service again. They likely operate downstream from a provider such as Bandwidth, Twilio, or similar. Their team can ask their upstream provider for a "snapback" of the number - essentially they can go take it back. That will leave you with your number back at the VoIP service to try again when you're ready :)

With all that said, I do have access to these upstream systems and some more advanced lookup tools. Shoot me an email (in bio) with your number and I can do some research for you if you want. Good luck!


(Warning: shameless self promotion)

I’ve run an app the last 8 years which is the same idea but lets you have multiple numbers, for as long or short as you want. Calling, texting, voicemail (with custom greeting), outgoing caller ID, etc.

There are unlimited plans for $9.99/mo or pay-as-you go plans starting at $2.99/mo which include a few minutes and texts each month but are primarily credit-based (about $0.02 per outgoing text or answered call minute; incoming texts are free)

Happy to answer any questions!

Thanks for using and recommending Unlisted! We added an Android version last year and both apps are under active development. I'm happy to answer any questions (or receive feedback about what we could do better) - [email protected]


I’m the founder of Unlisted (https://www.unlistedapp.com) and this is exactly the problem I was aiming at when building our private number service.

Unfortunately today, however, many sites will detect VoIP numbers and refuse to send messages to them. There are two reasons: 1) The app detects that it is not a “real” number and blocks its entry, or 2) the number is accepted but no message is ever received. In the second case, the “call with a code” option does usually work though. The reason is that short code providers negotiate delivery outside of the normal framework that long code (“normal”) numbers use. Most apps like Unlisted are using Twilio as a provider and these agreements just aren’t in place.

I’ve been running Unlisted for over 6 years so have a bit of experience around this space. Am happy to answer any questions!


Hi, I have some questions regarding your privacy policy. It appears that Unlisted maintains records of IP addresses, calls, texts, contacts, voicemails and lots of other metadata.

I admire the goal of trying to provide a convenient way to increase privacy when using SMS, but this feels a bit invasive. That's a lot of collected data. Unlisted has access to the entire history of all my conversations and calls. Why not encrypt most of the at-rest data with the user's password and decrypt it client-side? This is common practice for the more privacy-leaning email providers, such as ProtonMail. Similar SMS services have taken this approach as well, like crypton.sh.

You are leaving a lot of the privacy enthusiasts on the table (myself included). It may seem like a small market, but communities like /r/privacytoolsio are very active and constantly on the lookout for privacy preserving products.


The worst offenders are the ones that block Google Voice; As I understand it, Google Fiber/Google Fi users can't use these apps since the number system goes through G Voice.


SEEKING WORK - Remote // Berlin // Will travel in US or EU

Experienced (5+ years) iOS Developer -- How can I help with your app?

I have worked for startups and product companies in San Francisco and Berlin to both bring new products to market and iterate on existing apps. On top of that, I run my own successful app business and can fluently communicate with all stakeholders -- tech, product, business, or otherwise.

Apps I have worked on in the last few years have been featured in Apple's WWDC keynote, regularly ranked in the top 50, or were featured by Apple in the Apps of the Week or Best New Apps categories.

In the last few months I've come into projects, new and old, to:

- work with a designer to build an entire MVP based on his designs

- implement a major point-release for a Fortune 50 company's app that has existed since 2012

- take over a project for a major Swiss company to fix the final bugs and performance issues and bring the app to market

I am a US citizen living in Berlin and authorized to work in the EU (& the US). I prefer remote work, but for the right clients am willing to travel worldwide as needed.

SEEKING WORK - Berlin, Germany or Remote

Do you need an experienced iOS developer to build your MPV or take your app to the next stage?

I'm from San Francisco but have been living in Berlin since 2014. I've worked for startups, larger companies, agencies, and myself to build apps large and small, and now I'm looking for new clients.

SEEKING WORK - Berlin or Remote

I make native iOS apps for startups and product companies. My expertise is communicating with both technical and non-technical stakeholders to efficiently build an MVP with a solid foundation for future iterations.

In other words, clients praise me for my speed, communication, and pragmatic design decisions to get things done without delivering crap that needs to be thrown away in the next iteration.

What's my secret? Not only am I an experienced (5+ years) Swift and Objective-C developer, but I have also had my own successful app on the App Store since 2012.

Apps I create have been regularly featured on the App Store, and one had the honor of being presented in Apple's 2016 WWDC keynote.

My experience as an independent iOS developer, when combined with my previous client work, means I can own the iOS development process from any point between idea and your millionth App Store download, and I've probably seen any potential gotchas before.

If you are interested in working together, please say hi at [email protected].

SEEKING WORK - Remote // Berlin // Short-term Travel

I am an experienced (5+ years) Swift and Objective-C developer from California, now living in Berlin, Germany.

I previously worked at various companies in San Francisco and Berlin to build iOS apps which were featured in Apple's WWDC keynote, regularly ranked in the top 50, or were featured by Apple in the Apps of the Week or Best New Apps categories.

On the side, I run my own app, LineUp, which regularly ranks in the top 50 for the Productivity (Grossing) category and has grown to $58,000+/year in revenue.

My goal at the moment is to meet and work with interesting people, build their early stage products and MVPs, and find time to do the same for myself. If you think we would be a good match working together, please get in touch!
