[ plans for other devices ]

GNSS receivers have internal 4G GSM modems to simplify connecting to RTK networks. The iG9 GSM modems will work with most USA carriers except for Verizon.

You can activate your own cellular data service or you can use the GSM cards which we include with every most 4G/5G receivers. They will NOT work with 3G receivers.

If you choose to use our SIM cards activation will be very simple.

Our rates are very competitive, there is no activation fee and there is no contract:

Monthly
Data		 Activation Cost
paid annually		 Monthly
Cost		 Overage
250-MB $0.00 $240/year $20 $1.90 / 100 MB
1-GB $0.00 $270/year $22.50 $1.90 / 100 MB
5-GB $0.00 $390/year $32.50 $1.90 / 100 MB

We can bundle the cost of a 1-year's service with the cost of your equipment and your equipment will arrive pre-activated. Or you can choose to activate a data plan on the pre-supplied cards at any time.

Why purchase a data plan from iGage?

We shield you from a potentially frustrating activation experience

Commercial-grade SIMs

No setup or activation fees

No waiting for SIM cards to arrive, no charge for the bundled cards

The SIM cards are pre-associated to your iG9 head, all we need is the iG9 serial number to activate

If something goes wrong, we have access to the ATT backend network tools that allow us to actively troubleshoot your card, device, network connection and card status:

If you purchase a card elsewhere we are unable to help you because we won't be the account holder of your service.

Frequently asked questions

What if I go over my data limit? We will contact you before you use all your data. Service will not stop if you reach your allowance however, you will be charged for excessive use.

Can I increase my monthly allowance? Yes.

Can I move the card between devices?

  • GSM (aSIM): Yes, the card is registered to a primary device, however it should activate in other devices.
  • vSIM: Yes but you will probably need to contact us with the IMEI number of the new device each time the card is moved.

What is the APN, User Name and Password? Typically you must set  the APN to: 'dac.com.attz' and leave Name and Password blank the card should automatically provision.

What is the phone number of my card? The card is data only and has no voice or messaging features.

Is the IP address static? No, the address typically is double-NATted and can not be reached from a public IP. If your application requires a public-IP or a static-IP you need to purchase service elsewhere.

Is the iGage supplied service a good deal? If your data use is typical, our plans are extremely cost effective because they have a small, fixed, monthly (but paid annually) cost. If you are going to use more than 5-GB of data per month, then it may be less expensive to purchase an 'Unlimited Plan' attached to a typical voice/data/messaging plan. Even if the alternate 'Unlimited Plan' high-speed quota is used, the throttled speed should be sufficient for RTK/NTRIP use.

 
How much data will my iG9 use?

A highest data use scenario is a fully enabled GNSS Base (GPS + GLO + GAL + BDS + SBAS + QZS) receiver (like the iG9) tracking 31 satellites, all signals (L2C, L5, GLO-L3), broadcasting RTCM3.2 MSM. This configuration will transfer ~34,000 bytes of correction data per minute:
 
Extreme Use   Bytes
1 minute   39,000
1 hour   2,040,000
8 hours   16,320,000
20 8-hour days   326,400,000
1 24-hour day   48,960,000
31 24-hour days   1,517,760,000

Typical networks in the USA track GPS + GLO only and transfer ~18,000 bytes per minute while tracking 16 satellites:

Normal Use   Bytes
1 minute   18,000
1 hour   1,080,000
8 hours   8,640,000
20 8-hour days   172,800,000
1 24-hour day   25,920,000
31 24-hour days   803,520,000

250-Mb per month is plenty of data for most survey and engineering users, however if you plan on using the iG9's built-in hotspot choose a plan with enough data for the receiver and the attached computer's use.

 
Cellular Data Plans for other devices

We offer discounted data subscription plans on multiple carriers with no contracts, annual payments and easy configuration.

Our customers are surveyors and engineers with single receiver modems to large enterprise organizations with multiple devices. Our data SIM cards work with both GSM (ANET) and CDMA (VNET) SIM devices.

SIM cards are $5 each and are shipped by USPS Mail.

If you have a single modem in a GNSS receiver, an automated tractor, a security camera, a remote GNSS CORS station or even a UAV tracking device, we can provide simple, no-contract cellular connectivity utilizing the top networks at great prices with no setup fees.
