Any info on datajack compatibility?

I heard about the $40/mo no contract datajack service, which would be cheaper than the Sprint service I currently have. But I can't seem to find out whether the datajack would work on the cradlepoint routers. I wrote to datajack, and they said they had heard of some people with success but couldn't make any promises. Any info?

Cradlepoint does not offer support for Datajack at this time, also keep in mind datajack works primary off of T-Mobile Network. The Sprint Network you currently have is a bigger network.

There is a solution to this.

Cradlepoint does not (yet) support the USB modem (Option iCON 452) that Datajack uses*.

It is true that Datajack currently uses TMobiles 3g network for access.

So what you need is a modem that cradlepoint supports for Tmobile. Make sure it has access to the AWS frequency (1700mhz).

You may need to unlock the gsm tmobile modem if datajack is using a unique sim card, but a quick google search (and about $10) should get you an unlock code.

Once you have an unlocked tmobile modem, just remove the sim card from the datajack modem, or ask Datajack for a SIM card only (no modem) and place it in your new tmobile modem. You should have service.

*There is great speculation why Datajack went with the Option card, vs. using the card offered by tmobile. My theory involves the uniqueness of the Option 452 card. It is the only USB card on the market that supports ALL of the GSM frequencies (800,850,900,AWS-1700,1800,1900,2100mhz)

By choosing this card, if the Tmobile contract falls through, Datajack could possibly contract with another carrier, most likely AT&T (which uses 850/1900). The official Tmobile card would useless as it doesn't support At&t's 3g frequencies.
