Is there a piece of iron to forward calls from GSM (mobile network) to Skype?

Question

Skype

I'm leaving for a long time abroad on a business trip. I would not like to be left without a mobile connection. Roaming will be expensive. Yes, and a local number must be left, a lot of customers stay here. I don't know much about telephony.
Actually, to the topic. Tell me, dear experts, is there any such "box" where you could stick a SIM card. And so that this box forwards an incoming call via an Internet channel to a Skype account or to any other program for IP telephony.

Answer 3

I would:
1. Take a local number from the operator's IP
2. On the mobile phone, turn on call forwarding to it when the mobile phone is turned off
3. I would take a foreign SIM card "there"
4. Set up call forwarding from the operator's IP to the "local" SIM card.
It will turn out not very expensive, and you do not need to buy any hardware, set up servers.
If it works, as xtreme recommends recommends , setting up SoftFon is generally Happiness. Calls are even cheaper.
It depends on what mobile operator you have - there is, for example, a multiphone from Megafon - it will still be easier.
