How do they acquire a large number of cheap phone numbers?
Websites that provide SMS verification services, like https://sms-activate.io, obtain their phone numbers from where, and how can one acquire cheap phone numbers in bulk?

corruption in mobile operators
those are VoIP. There are companies sell those.
Which countries and how many numbers are you wanting?
They sell people's privacy for money.
Many of them are not. These guys even engineered specialized hardware to insert many SIM cards into a single hardware
A lot of mobile companies offer wholesale services, allowing you to resell their voice, SMS, and other services. They provide number ranges that you can purchase.
Keep in mind that the mobile company is listed as the carrier, and abuse or spam complaints are sent directly to them. Some companies take issues like forged sender spam and fraud very seriously, so it's wise to negotiate an abuse handling procedure as part of the agreement.
You can easily look up the carrier (wholesale provider) if you know the phone number: https://gatewayapi.com/docs/apis/rest/#hlr-and-number-lookup.
You'll get VoIP/API access to the mobile companies' systems, as mobile/SMS modems are too slow for 99.99% of use cases.
These services are easy to find—just Google the company name along with 'wholesale.'
Do you know which platform offers cheaper wholesale prices?
Any sources or links to that, I would love to see one of those?
Handling physical SIM cards and dealing with coverage, roaming and international delivery just to be able to send sms must be some kind of record in stupidity. I've never seen a provider that does not provide wholesale trough API or voip so why use hardware at all? I mean, even if you use actual SIM's, eSIM has been a thing for quite some time so still no need for hardware.
They could be using software eSim

no need for hardware…? do cell towers work through prayer?
Holy shit, that's the craziest thing I've seen in a long time. Never underestimate what may come out of a chinese basement somewhere.
I was of course talking about the client side of things, or do you buy your own cell tower too when you send sms?
this is a nonsensical question so ill assume you are a nonsensical person
A GSM modem can only send approx. 10 SMS messages per minute.
You asked if cell towers work through prayers and you call me nonsensical? Yeah, right, that makes sense.
I run systems that sends thousand of sms's per week and I have zero hardware for that, I don't even own my own cell tower and I've never prayed so one of us clearly does not know what they are talking about.
so youre a dweeb using an sms gateway api good job
Not at all, but good guess.
only dweebs use the front door. the real use a phone farm in rural manila operated by slaves earning $2/hour
We clearly have very different views on what constitutes a "dweeb".
I wish I could use phone farms in third world countries, but I'm not twelve anymore.
Do you want to build a service like this or do you just need some numbers for yourself?
Personally i use sim cards from the netherlands with a bunch of dumb phones to get my codes. the sims don't expire, you only have to call the mailbox every 6 months, for example.
I want to set up a service where simple virtual numbers can be used, but I’m not sure which service provider I should look for to provide a stable API for receiving verification codes.
If you want to set something up that relies on VoIP - not sim cards - have a look at:
MVNO aka neo telecom operators.
Specs: https://www.skylinecentre.com/productDateil?id=3&keyId=39
Network: 2G2G and 3G have been shut down in many countries, and some have started phasing out 4G.
Does your outdated hardware come with a time machine?
spend more money then? not my hardware, i googled “bulk sms machines” and found that
It's funny that you still don't get how insanely slow SMS modems are.
4G modem Example:
https://www.smseagle.eu/products/eight-modem-pro-series/#1686141979915-bf171b2d-365c
Price: €2000
THROUGHPUT: MAX. 240SMS/MINwhat the fuck are you talking about? spend more money then cheapskate, i dont deal in hardware and dont give a fuck about your opinion
Oh, so you'd rather spend as much as you can on an unsustainable, outdated solution instead of getting a direct connection like any sane person would?
Damn, you're being really stubborn and naive.
