This is a wifi model it does not work over a celular data network. To use the online fetures you'd have to have it connected to a wireless network.

No, you don't have to have service, unless you want to, you can use wifi, or get a monthly plan

No, the Datablaze service does not require any contract and service fees are billed monthly. You can cancel or suspend at any time.

Yes, the 500MB per month plan is totally free. You'll have to be careful to monitor your usage so that you don't go over that limit otherwise you may incur charges to continue your service beyond the 500MB limit. If this draw for buying this modem is the free service part then it makes the most sense as a supplemental internet service that you use once in a while on the road.

I believe that there will be a $2 or $3 monthly fee for the t mobile cell service in addition to whatever you and the control panel use to contact each other. I have had mine less then a month so far, so I can not verify yet about the monthly fee for the cell service.

there are no fees if you own your own modem but if you do not , that fee is determined by YOUR local company, its different for each company

Yes I have used this service for over a year now on several products. The fee is one time and is your extended warranty of sorts for your device.

No fees at all. But make sure they have your channels. I lost 5 channels after I bought. Buy 509 is newer one.

Nope no fee! I've had it about a year now. You do get charged a certain percentage per transaction but it's fairly small.

Yes you do need to pay a subscription. However, with some bands they offer 3 month free trials.

No monthly fee. You need a controller unit as a base, then you add as many accessory devices you want.

No, there is no subscription fee even to use the app while away from home (assuming you have a data plan with your cell phone carrier)

You will have to pay a monthly fee once the GPS device is activated. But it's not a long term contract, it's month to month. By the way, the device and service work great. I found it to be worth the money.

It depends on your phone carrier and who you have service with. You should be able to with additional fees.

Have never used OnStar; I am using initial service; I read that to have availabilty of more frequent updates than the free annual, then there is a subscription charge.

No. There were no additional charges. The following month I switched to the $30 per month plan by selecting it online (it defaults to the $50 monthly plan). No phone calls, misunderstandings or hassles.
