The just-announced Surface 3 tablet will be sold in four different versions, two of which will have LTE wireless support. However, those two models won't be available until later this summer. Verizon and T-Mobile will offer those two Surface 3 tablets for sale in their stores.
According to Re/code, Microsoft plans to add more carrier support for the Surface 3 LTE models, but there's no word on when that might happen. The pre-order page on the Microsoft Store website shows that while the Wi-Fi-only models will start shipping May 5, the LTE versions will ship on June 26. In fact, pre-orders for the LTE models are not yet live; the site simply offers to give shoppers an email alert when they do go on sale.
Just a reminder: The Wi-Fi-only Surface 3 will be priced at $499 with 2GB of RAM and 64GB of internal storage, or $599 with 4GB of RAM and 128GB of storage. The LTE models will be sold for $599 with 2GB of RAM and 64GB of internal storage, or $699 with 4GB of RAM and 128GB of storage.
