Upgrade question-Whata CDMA and GSM

I recently upgraded by blackberry bold to 6.0 and it as me a question.  I don't even know what it means so I said no!  I think this coded language is a bit assuming.  Here's the question.

 

What does this mean ?

"you have inserted a SM Card. Would you like our blackbery to automatically selct CDMA or GSM based on the network availability?"

 

I think SM is my memory card. so what is CDMA or GSM and what would happen if I answered Yes!

 

Will this end up costing me extra money?

 

I hope someone can help me out, I spent 25 minutes wading through Support trying to get an answer.

Please use plain text.

Re: Upgrade question-Whata CDMA and GSM

SM, you mean SIM card, not the Media Card, but a card the carrier or you insert which gives you access to other cellular bands if you are traveling out of your home country.

 

You failed to say, but what model BlackBerry Bold do you have? I assume the 9650 from Verizon or Sprint, which are both CDMA network providers. Since most of the rest of the world uses the GSM network, if you were to travel to, say Europe, you would need access to the GSM radio bands for your BlackBerry to operate.

 

So, Verizon includes in its quad-band model devices, such as the 9650, a SIM card, or chip, to enable that.

 

For your situation, you can tell that warning message either yes or no, doesn't really matter unless you are about to travel to another country. Personally, I'd say No, and leave it on CDMA.

Re: Upgrade question-Whata CDMA and GSM

Hello,

 

Nope...not an SM card...not your memory card...but a SIM card...see these:

It is the card that identifies your BB to GSM networks. CDMA networks do not rely on the SIM to identify the BB. On BB's with multiple network (e.g., GSM and CDMA) capabilities, the prompt is exactly what it means...do you want the BB to automatically select your carrier network or do you want to manually select your carrier network?

Depends on your contract with your primary carrier. If you have free roaming, then you'll be able to roam on other networks for free (pretty rare, btw).

 

I suggest you contact your carrier for formal assistance with properly registering your BB onto their network.

 

Good luck!

Re: Upgrade question-Whata CDMA and GSM

It's a routine question I get often on my CDMA devices, and unless you roam into another country, there's really no problem.

 

If you're traveling internationally, you'll want to call your carrier anyway and set up an international calling and data plan.
