Simply buying modem doesn't allow you to call/sms etc. You need a internet/voice call subscription from a service provider. Not sure which region you are from, check with your Internet service provider and enquire about the USB modem which will support all these features if you buy from ISP via their dialling software etc.


i don't want have 3g internet usb key. I want a gsm key like this https://www.amazon.fr/Tri-band-Modem-Phone-Radio-1900Mhz/dp/B00LSQWXRS

but i want software with this for call or send sms with key. I want use my sim card

That's why you need a USB key from your phone provider. Those are all-in-one solutions. The USB and SIM card will work seemlessly without ANY problems, as will the sofware for voice/sms. Example here: http://www.vodafone.com/content/index/what/devices/vmb.html

Doing it all apart and by yourself is asking for a world of hurt.


i read vodaphone faq and i have this :

Can I make voice calls using my Vodafone Mobile Broadband SIM?
No. The SIM in your device is only able to send and receive data and SMS text messages. You will not be able to use it to make phone calls.

I want to make voice calls

Do not waste time on this project.

Technically, it is not feasible as no carrier will allow to dial a phone call direct from your computer.

You can only use VoIP call using a 3G/4G USB modem. Just subscribe for SkypeOut and use Skype to make the phone call.

Telecommunication is a regulated industry and the authority requires the carrier to maintain a registry of their subscribers.

So, users can only use devices running mobile OS to make a phone call if you want your call to route through the cellular network, not the IP network.


I already created a program to send sms with a controller like this :

I do not need to have authority require and I do not need to have mobile operating system ( i had use a small linux OS).

If no solution exist.  I programming my own solution based like this embeded controller card.
But i'm very surprised that is not exist.

No such software exists because of the law. You can create any tool but you need your carrier to allow your device to be on their carrier network. You are just naive to think in such a simple way.

All mobile phone manufacturers have to comply with the law and you will not be excepted and you are just wasting your time as I am sure you cannot file a complaint to your carrier for not being to make a phone call via a computer.

What the closest thing to do is to pair a real mobile phone via Bluetooth and initiate the phone call from your computer.

It is fine that you do not trust my words.

I just do not want you to waste your time as it is a common sense for any educated person.

Just look up Regulatory information from any smartphone and you will see the content like the screen capture above.

Are you capable to get your device approved by the authority?

I guess not unless you are very rich to employ a team of professionals to do the work... But, in such case you will not ask this question.

Finally, sending a SMS is very different from making a phone call.

Can you figure out the difference? All USB 3G/4G modem dongle or Pocket Wifi do not carry voice communication. Do you know why?
