Probably Tmobile bc my cuz had tht fone and she had tmobile but could be wrong?
No, it should not matter. As long as you have a Sidekick phone and you want to use internet on it, then register the phone for a Sidekick Data plan.
If you want to use internet on your Sidekick 08 phone, you would Sidekick Data plan for that.
No. You can use the sidekick for texting and phoning and elect not to have the sidekick package which costs an extra 20 per month. It's a cool phone and t-mobile has some pretty nice rates for phone and text only.
You can use your Sidekick 3 phone in select markets outside the USA. Make sure that you have a roaming plan, otherwise you will be hit with large fees.
She uses the Sidekick 3, but they don't sell it anymore. You can get the Sidekick Slide, the Sidekick LX, the Sidekick LX Tony Hawk Edition, or you can get the newest versoin of Sidekick: the Sidekick 2008.
Any cell phone that is unlocked requires a SIM card to work. If you own a Sidekick cell phone that is unlocked you are able to use a carrier other than T-Mobile. For this reason, it will require a SIM card to work.
The Sidekick can use aftermarket memory cards, as well as carrying cases and car chargers.
sidekick lx 2009
She uses that Sidekick 3
No you can't,i just call the company because i have the same problem,and they told me that i can,t even use my sim card with another track phone,so is nothing you can't do.
First, you would need to unlock the Sidekick. And make sure that the SIM card you're using is GSM-based. Now, once the Sidekick is unlocked, then you can use the phone for calling and texting only. You may not be able to use the data on your phone even if you register the phone for a data plan. Sidekick phones have special data plans that only T Mobile can support.
he uses the tmobile sidekick 08
