Simple Mobile is testing the multi-month plan waters. The T-Mobile based provider is now offering 3 months of unlimited talk, text and data with the first 12GB of data each month at LTE speeds for $100. That works out to an average cost of $33.33/month. The plan is regularly priced at $40 month or $37.50 with auto pay billing enabled.
Details on this new offer are rather scarce right now. It is a limited time promotion that is scheduled to be available until 2/4/19. The offer is not yet available on Simple Mobile's website but it can be found at independent dealers such as Let's Be Wireless which is located in Oakland Park, Florida.
This new offer from Simple Mobile actually builds on another promotion that the MVNO is currently running. The $40 plan normally only includes 6GB of data but is scheduled to include 12GB with each renewal until at least 1/31/19. I imagine this deal is going to get extended to better coincide with the new multi-month offer.
Besides the talk, text and data, Simple Mobile's multi-month plan also comes with unlimited international calling to over 60 locations. Unlimited international texting and mobile hotspot are included. The plan also provides its subscribers with international talk, text and data roaming in 16 Latin American countries. Taxes and fees cost extra and are not included in the price.
I can confirm that Simple Mobile does support HD Calling and the sound quality is amazing. Even in rural, middle of the no-where places of SE Kansas and SW Missouri.
