 Pro/Con of “Privacy” Phone Numbers/Services

JMP.chat
Type: Number
Pro: No KYC VoIP to XMPP (or Matrix) for anonymous Bitcoin, so you're using an open source client
Con: Only US and Canada numbers.  They're just reselling Twillio VoIP, which means that not only are you just paying more just for anonymity, but many services recognize these as Twillio VoIP numbers and will block you.
Solutions: There exists the possibility of buying a real world physical SIM and then transferring over service to JMP VoIP.  But you’re better off using 1 time burner services for most account registry.

Hushed
Type: Number
Pro: No KYC VoIP for Bitcoin, similar to JMP.chat
Con: Uses their proprietary client which isn’t private through the Google Play store.  I’d avoid Hushed.

Silent Link
Type: Number + Service
Pro: No KYC Crypto SIM card that separates billing and identity from the literal cell tower carrier
Con: Uses eSIM which requires Graphene’s Google Push service sandboxed.  No outgoing calls.  

Calyx Institute Hotspots
Type: Service
Pro: No KYC WiFi hotspot for Crypto
Con: It’s just reselling T-mobile service, so if you use this in your home and your home is KYC, then T-mobile will likely figure out that it’s you since celltowers see geolocation.
Solutions: You can avoid this by putting the hotspot in a faraday bag, and only using it outside your home.

MySudo
Type: Number
Pro: Multiple burner VoIP lines
Con: Requires Google Play store JUST to PAY for it, but then can be used on a degoogled phone once you add credit.
Solutions: This can be sandboxed or put on a separate old device and you can use bitrefill to buy the credits with cryptocurrency

SMS.usmobilenumbers.com
Type: Number
Pro: Quick easy cheap burner anonymous SMS verification for cryptocurrency.  It’s real SIMs and not VoIP.
Con: US only.  They resell the number for OTHER services, which MAY trigger anti-fraud for SOME services including Zelle, eBay, PayPal, LinkedIn, and others.  So you risk a ban on accounts.
Solutions: Avoid putting money in any account for a few days to see.  Use a residential proxy IP instead of a datacenter VPN, especially for eBay.

VirtualSim.net
Type: Number
Pro: Great for abusing foreign numbers in poor countries such as Cambodia or Ukraine for Signal or Telegram.  Quick easy cheap burner anonymous SMS verification and/or longer term monthly numbers for cryptocurrency.  It’s real SIMs and not VoIP.  Their customer support is excellent and we highly recommend them for Telegram verifications.
Con: They may loose access to the burner number after a period of time (like a year) where you can’t renew and someone else COULD potentially verify the number.

Crypton.sh
Type: Number
Pro: Huge amount of countries for real SMS anonymous crypto.  Get sought after Western European #s here that normally have strict KYC rules on physical SIMs
Con: Overpriced setup fee for 1 time SMS verification, but if you actually live in (or desire) that country it’s okay.  There’s no real purpose in all their “at rest encryption” advertising, because SMS is unencrypted transport.

 Great list. Thank you. Currently trying out silent link while roaming and it's been 👌 
 Thanks for this! 
 I used jmp.chat so my daughter could have a phone number for calls and sms on her wifi only tablet, then set her up with signal. Worked great, good customer service. Sms is a little weird because the receive address isn't just the phone number, it's more like an email address, but it works. Thanks for the list and detailed pros and cons! 
 If you use the Cheogram app, you can sms just like normal, you don’t need any weird addresses 
 Great list, thank you. 
 Bitrefill too - esims paid for with ⚡️ and KYC-free 
 Cool. I like SimpleX chat... no phone number required. 
 Great post, thank you! 
 I have recently seen some decentralized identity methods, such as the open source project "session message", an open source project from Australia, which can be registered with end -encrypted and without mobile phone numbers.

I used the translation software. If the language is not smooth, I'm sorry. 
 Are these something like PGPP from Invisv? I saw some time ago Edward Snowden recommended invisv, since then I am using only relais from invisv, because I dont have degoogled phone yet 
 That doesn't switch IMEI so I can't recommended it.  All that kind of stuff is a waste without a degoogled phone 
 I probably will donate myself one degoogled phone from your website for christmas. I hope I dont get trouble with customs 😂 
 No issues w customs, we promise.  Unless its Russia or Ukraine, Iran, ect. we can't do for that reason 
 What's wrong with Ukraine? Delivery (e.g. Nova) works here despite the war. Are you putting us under sanctions in addition to our own government?
I think Ukrainians need private communications more than anyone else right now. 
 Does ANYTHING switch IMEI except GerdaOS and the Mudi firmware? 
 The question isn't how to switch imei because anything could do it with the right software and knowledge. The question is how you're going to rotate billing plans without the entity providing that connecting the identity 
 PGPP has decorrelated billing from service. 
 See my recent notes. 
 They nullify IMSI, which is a big improvement, but IMEI seems to be on their to-do list. Other services switch IMEI? 
 @snowden nostr is slow. Someone shared information from Over 10 years ago. The text from my manager reads "Rebekah please go to that room when it is on the board do a terminal clean the patient had bed bugs. I will not clean it I'll send someone else to clean it. If I can do rooms with dead people to help my coworkers out when they can't handle something why are these mean girls still only doing it to me? Why can't I be shown same kindness? 
 Don't forget Purism AweSIM 
 Yeah but if you really want to be anonymous

You're going to have to pay a homeless person who's on drugs or just forgetful to buy your SIM... 
Not near where you live.

 one I like recently is Cloaked -- phone numbers, emails rolled into one

 What is end goal? Private voice convo? 
 Super helpful. What about taking your physical SIM and transferring to Signal ? P.s. I owe you a follow up email. 
 I'm confused. physical sims work on signal
If we spoke via email, please use the protonmail, the other one had issues 
 I see. Was confusing the issue a bit. Trying to solve for moving existing numbers (tied to biz & personal) into an anonymous environment and off mainstream carriers 
 interesting, what DNS? Quad9? 
 It's working today.  
 Ok thanks for reporting.  Yeah we got false flagged on a blacklist.  Tor onions should always work regardless
