MAYSVILLE, KENTUCKY – Dec 11, 2023 – Today Carlson Software begins worldwide shipments of a SIM card, which when activated, includes data service from over 300 worldwide cellular networks. Previously available only in the U.S., the SIM card, from RTK Mobile, works in 150 countries, almost* anywhere on earth a supported cellular data network signal can be found.

“RTK Mobile’s multi-network SIM cards were a welcome connectivity solution when they were released in the United States,” said the International Sales Director for Carlson Software, Scott Griffin. “We’re pleased to be offering the same option for all of our customers, worldwide.”

Having a SIM in Carlson hardware provides numerous benefits: In addition to the convenience of having email and other internet capabilities in the field, tablets with an internet connection pass RTK corrections through to the GNSS receiver. Alternatively, a GNSS receiver with an enabled SIM card can independently get its RTK corrections from the internet.

The RTK Mobile SIM card intelligently connects to the strongest available supported local cellular network, with no roaming fees. For example, in the U.K., the SIM will automatically connect to the strongest local cellular signal among Airtel, EE, Hutchison, Manx, Telefónica or Vodafone. For users in Brazil, the carrier selection includes Claro, TIM and Vivo. (See RTK Mobile’s full network list at rtkmobile.com/networks)

In May of this year, Carlson Software began shipping these SIM cards to its U.S. market. RTK Mobile customers in the U.S. can seamlessly roam between the major U.S. cellular networks: AT&T, T-Mobile and Verizon.

“The SIM cards Carlson ships in the U.S. are identical to the internationally-advertised SIM cards: They have the exact same features and compatibility,” said the Chief Engineer for RTK Mobile, Benson Trent. “Existing customers don’t need to upgrade, they have the same access to our vast network of over 300 carriers in 150 countries.”

Carlson Software is including a free unactivated SIM card from RTK Mobile in all worldwide shipments with qualifying SIM-ready hardware. Existing Carlson customers can request a discounted SIM card from rtkmobile.com using promo code CARLSON.

Customers can activate their SIM card by purchasing a data plan from RTK Mobile. The plans start at $25 USD per month for 1 GB of data. Detailed video tutorials for activating and setting up the service on devices like the Carlson BRx7, RT3, RT4, and RT5 are available on the RTK Mobile website.
