    Is it possible to use 2 different SIM cards with a specific holder with the Treo 650? I'm going to have a business mobile line and I don't want to carry 2 phones...

    Don't know what you mean by specific holder.

    I am thinking you don't want to swap SIM card and want both SIM to be actively connected. Treo has only one tray.

    My carrier offers multi-line SIM Card that can hold two line in one sim card, which is great for having business & personal lines in one device.

    But, can TREO 650 handles this type of SIM card that carries 2 lines ?

    Probably, most devices can, but no US cell providers do...

    fadzrul,

    Which carrier allows you multi-SIM?

    Obviously they don't have the Treo, but Nextel offers 2-lines on one SIM. Many who I work with have activated a 2nd (personal) line on their company phone, which is then direct-billed to them.

    Yes, it is possible to have 2 SIM cards in the Treo. I have a post in HoFo. If you are interested, read this thread.

    Thanks for your feedback, it is quite intersting even if I'm hesitating as it appears to be quite risky...

    Multi-SIM and Multi-line are NOT the same.

    Multi-line is more than one phone number associated with ONE SIM, both numbers are of the same provider.

    Multi-SIM is two SIM, of a different provider in one phone. You'll have to use some sort of an apaptor -> http://www.cellphonegeek.com/prod_li...card+Utilities

    SIM cloning no longer works on new SIM cards because most likely they are V2 SIM Cards.

    I got my gereration 8 in yesturday and as far as i can tell it works great.
    I wish i had got the sim card cutter since i dont like cutting my own.
    I can switch between the two, all the treo has to do, is the phone app cuts off and on again.
    You switch it using the sim services menu(took me forever to figure that out).

    One thing i have noticed is that instead of showing cingular as the network name, It shows digits. It might be because i have a old AT&T card in it at the same time.

    I will do some more testing and report back.

    I am using a 4th gen and it works great. I wonder what the advantages are in using the 8th gen vs 4th gen. I switch numbers using the same technique as johnnytk36.

    From what I can see, Gen4, Gen6 switch by sim card number (card 1 or card 2), whereas, Gen8 switch by phone number.

    I just ordered the Gen8, hope it works well for me. Let you know..

    My T-Mobile SIM allows 2 lines of service. No need for 2 SIM cards, or re-starting the radio.

    If a call comes on either line the phone rings and shows which line is ringing. When calling, the Treo will use the current line. To change it, just select it from the menu.
