Saving money on a data only SIM card is easy with AT&T MVNOs, their low cost plans and the same quality coverage means there's no sacrifices.

You could even opt for a cheaper plan by choosing a set data limit. On average we only use around 3 to 5GB of data per month, so do you really need all that unlimited data? You can estimate your data usage with our free tool to find out.

If you've not found a deal with AT&T, you can compare more data only SIM cards from T-Mobile and Verizon.
