Hi there,

are there any known risks using SIM-Card-adapters like TurboSIM or StealthSIM like sniffing PIN or voice-data.
Is this possible at all?

the only thing i heard but wasnt confirmed is that there might be roaming costs sometimes because your sim card is detected as a foreign simcard insied your homecountry....

Perhaps someone havin a turbo sim in action for longer then just a few days and got his first invoice can tell us more...

I haven't heard anything about the roaming costs myself, but:

- You need to cut your SIM card to make it work with Turbo or StealthSIM's. I like my iPhone, but honestly, phones get better all the time. I'm not gonna cut my SIM to make it fit just for one phone.

- I don't know about the StealthSIM, but the TurboSIM is notoriously fragile. Push it in to hard and it breaks. So be careful.

yes the sim cutting is also the point that i dont like....

What? Can't you just go into your carrier's store and ask for a new SIM-card if you should mess one up? It's just plastic.

no in germany for example a new sim costs 25€

I believe if you cut its tiny part,it will work with any phone still,or, atleast thats what i ve read.

It works in any phone after the cut, so it's not a problem.

The way TurboSIM and other similar devices work is by sending a "fake" ICCID to the phone during the initialization phase one, so that the phone only and not the network will be fooled by interpreting the SIM as being from AT&T (it can work also with O2-UK and T-Mobile-DE and maybe Orange-FR).

So there is NO way a network will see the phone as a roaming phone. If the network assigns your phone your number, it's because it sees the correct identification. The possibility of the network seeing these phones as roaming devices is merely a urban legend.

Also, SIM cards cost money anywhere but it's not a big deal. The real risk is breaking the pigback SIM such as the TurboSIM.

I've never used or seen a SilverCard/GreeCard/SuperSIM, but I suspect they are a new SIM card as a whole (they clone the whole SIM), so it's not that complex. But I've heard it's more complex to setup and use.

No, I'm positively sure you would never have to pay for a sim card here in Sweden. I have picked up SIM-card when I have lost my cellphone or when it was stolen. In fact, most carriers will offer free Sim-card pre-loaded with something like 5€ as a marketing trick. You can easily get 20-30 of theses free SIM-cards at times but too me it's not worth the free calltime as you get a new number for each SIM-card.

So if the carriers want money for giving you a new sim it's really bad service and a rip-off as they cost the carriers practicly nothing.

Promotional SIM cards with a new number is not the point. What we are discussing is what carriers call a "recovery blank SIM card", that is used to "recover" your phone number in case of a SIM failure or if the phone was lost or stolen.

My carrier will give a free SIM if the customer can prove that the phone was stolen (with a copy of the police report). They call it a courtesy recovery SIM. Otherwise they will charge around 5US$. It's not only the cost of the SIM, but the fee for activating it to your phone number, that may or not have a cost depending on each country cell phone regulations.
