Looking for sim card device that can do this...

jamie3000 · Apr 12, 2019

I'm looking for a device that I can slot in 100 sim cards and then slot that into my phone's SIM slot and it will rotate around the sims.

Then my app can read the SMS on each SIM and ping it off to my server.

This is for phone verification lock automation.

Anyone seen anything like this? I could built one with enough time but want to see if there is already an existing product out there.

I would like to up the thread as I'am looking for the same device.

Did you or anyone of you guys here at BHW found the solution for this?

Thank you in advance for any useful answers.

The nearest thing I have seen to it is a phone case that contains two SIMS that you can automatically switch between. So I am sure the idea is possible.

If you had a device like what you describe, it would be very cool and very useful.

Got it. Thank you

Actually no need to find the phone itself, it could be any solution with sim bank for 100+ sim cards and gsm-shield in order to have an opportunity to work with sim cards automatically. Professional SIM banks cost too much and that's why I'm looking for the solution.

There are some custom devices (based on Arduino, Rasb Pi, etc.) like SMSPVA device offered.
I would like to find such solution. I was even ready to purchase SMSPVA device, but as far as I know it is programmed on low level to be used only with their service but not for personal needs

Did you ever find a solution in the end?

@jamie3000 did you ever get rounding to fonding anything like this or building it, out of interest?

I didn't but have a look at @lucky.sparks journeys that might be helpful for you

What are you looking for is called SIM bank and there are models with 32, 64, 128 SIM slots. Also you can make use of some GSM gateway like Dynastar or Yeastar.

Just look for devices that have API so you can hook them up to your current setup.

I'm no hardware geeky, but can't GSM modems do the job ? they basically come with a built in software that supports API calls, and you can set it up to your server.

Code:

They are good for a setup with few SIM cards or some home lab to test idea but not for production with 100+ SIM cards. (4g proxy setup is another idea but we are not discussing it here).

To manage such amount of SIM cards one must have centralized software solution and hardware management because this is not easy task to do. E.g. In my country providers are “killing” SIM cards which are used in GW’s so i have to manipulate with HW (like IMEI change, etc.) to make it work

Did anyone tried such a device before? I've seen such devices in news every time there is a supposedly a troll farm somewhere and police raid it.
The criminals are using these to ... create accounts and spam social media I guess? Not sure if the internet connection is more important for them or phone number verification
