By 2019, the LTE-capable tablet market has evolved away from Android in my opinion. Features to consider include:
- unlocked LTE modem (AT&T, T-Mobile, etc.)
- Windows or Linux (allowing for creative activity–coding, art, robotics, etc.)
- cost ~ $400
- microSD slots to expand storage cheaply
We don’t recommend the ~ $100 tablets in general due to poor display resolution and slow CPUs.
Starting at $400 is Microsoft Surface Go among other Windows LTE tablets including Asus Transformer. Next up in price range are the Surface Pro tablets (don’t forget to include the keyboard price).
Get more cost effective electronics
Typically look at last year’s models (new, and especially refurbished) to get them at about half the price of this year’s models. For refurbished electronics, the “bathtub curve” of early failure has already been worked out. This is one way the average person can avoid becoming trapped in debt.
We no longer recommend Android tablets in general because they are not as well suited for creative STEAM work, especially a concern for children. We would like to see children become more creators than consumers.
Nvidia Shield Tablet K1
The Nvidia Shield Tablet K1 (and LTE version) was discontinued in 2017. The Nvidia Shield Tablet LTE also had Android 7 and was one of the best deals in tablets from its July 2014 debut through 2017. The Nvidia Shield Tablet K1 and LTE versions were on Android 7 Nougat from the factory. Lineage OS 14 is available for Nvidia Shield Tablet.
