I was looking for an inexpensive cellphone plan for my 2 kids and found that Tello is offering a free data promo at the time which is amazing and will save my kids' summer.
The plans start at $5 with 5 GB free for first month. Then just change to whatever data allowance you want to have, e.g. for month 2 I will switch back to 200MB with 100min and 200 text for $9 per month.
Use code 1DATAMIX or go through the link on the Tello promo page https://tello.com/promo/data
As for the Tello quality. I am with them since RP folded and like their service.
Cool off with a fresh offer!
Create your perfect plan mix by choosing your ingredients: minutes & texts, and make it as sweet as you like by adding data absolutely FREE, so you can taste the full Tello flavor.
Here's the recipe for this COOL offer:
Take one smart newcomer that switches to Tello starting July 17, 2017
Add a phone plan with mixed minutes, texts & data of $10 or more in any combination
Stir in one juicy coupon of 100% free data: 1DATAMIX
Enjoy this limited promo cocktail for your first month with Tello
