A device to manage multiple SIM cards?

One way to do this is to:
  • Buy many "SIM800L" modules (they're like $4 per one, should be cheaper if you're getting them in bulk), each of these can store a single SIM card.
  • Buy AVR micro-controller (~$2, might need couple of these)
  • Buy ESP8266 WIFI module (~$4, so you can control the device from a network)
So the cost of materials would add up to about (not considering bulk purchase, I'm sure the price can be reduced by 1/4 if purchased in bulk):
( 100 * $4 ) + $2 + $4 + $20 (wiring/resistors/led's/case) = $426 + Work (For a device which supports 100 SIM cards at once)

It would probably take about a week to build and program such device, depending on the requirements. If you're interested drop me a PM, I'm a programmer/electrical engineer.

Hey @Nerva as already stated above about smspva device. You can get yourself custom built, get in touch with someone who works with embedded electronic projects. I know this can be done as I have worked on some college projects in the past, using the gsm module. What we did was simply using the module available in the market. But as per your requirement you can get a custom built device.
 
There is no need to get 100 sim cards, there is an easier way with no costs. PM me I will give the name.

I have been using it for a while, works like a charm.

This.. its called modem pool.

I don't reveal certain tools I use to the mass public. That is the reason. Not here to coach or guide people, time to time If I see someone in need, I will lend a "hand"
 
Alternatively you can just verify the accounts by using the codes sent to you by the person with the simcards and they keep they safe for future use... I have done this before.... And it worked

Did you ever build this? Sounds really interesting
 
Search 'Sim Bank' or 'Sim Box'. That's where im at, I'm also looking for a good solution.
 
You need a sim bank u can get for 8 or 16 ,32 ... slots but if you dont need much slots just get cheap android phones
 
Is there a way to manage those simcards but also use the Sims as individual 4g proxy connections that I could access with any emulator?

What I want to do is manage 50+ "mobile" fake identities and then perform actions with them all through one device/computer/VM.

I'm planning on using these accounts to write online reviews and run social media accounts. Anyone with suggestions I'd be very interested. Willing to pay.
 
Hey guys,

Interested in same.

Is possible to host USA sim cards outside of US? Looking for buy usa sim cards with lowest monthly plan and do a little farm.

Which sim cards do you use?

Hey man, were you able to find a solution to finding USA sim cards? Im also looking for the same,but havent been able to find anything too affordable yet.
 
You can GSM modems. They come in 8, 16, 32, port +. Usually they come with an in house software so you don't need to buy a new one.
