Right now we don't offer any "add-ons" service for active plans but you do have 2 choices, depending on whether you wish to keep your existing billing date or not:
If you don't want to change your current billing date, then you can buy Pay As You Go
credit which can be used for US calls, texts, and data, as well as for international calls & texts. This will see you through to your automatic plan renewal date.
Pay As You Go credit is available for 90 days and then it expires.
Many customers use Pay As You Go as a backup to their plan, just in case they reach their monthly limit of data or minutes before the automatic renewal date.
Others use Pay As You Go for their international calls because of the great international calling rates to places like Cuba and other countries not included in Tello plans.
If you are OK with changing your current billing date to today then you can early renew your current plan or purchase a different plan today.
Log into your online Tello account
and you will arrive on the "My Tello" - "Dashboard" page.
To early renew your current plan click on the "Renew Now" button and follow the prompts.
To purchase a new plan click on "Change Plan" and follow the prompts.
If you choose either of these "Renew Now" or "Change Plan" options, then your existing plan will be canceled immediately and replaced with the plan you choose today.
You will be charged today for the new plan and renewal will be in 30 days' time from today.
If you want a new plan to take effect toward the end of this billing cycle, you need to change your plan at least 24 hours before your next due billing date.
There is no option to change your plan today to take effect on the next billing cycle.
If you have run out of data balance then remember all our data plans include Unlimited 2G data after you've used your 4G LTE/5G balance (this disables Hotspot).
For good data speeds however you will need to buy a new plan or Pay As You Go.
