You have 3 valid options, depending on whether you wish to keep your existing billing date or not:

Option 1
If you don't want to change your current billing date, you can add more data to your plan by purchasing a Data Add-On from your online account or by texting "ADD1GB", "ADD3GB" or "ADD5GB" to 800.
A Data Add-On is a data top-up that you can add to your current plan. Regardless of the date when the Data Add-On was purchased, it will expire on the same day as your current billing cycle.

Option 2
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.
You can top up your PAYG credit by sending an SMS to 800 with the text "ADD10PAYG" or "ADD20PAYG".
Pay As You Go credit is available for 90 days and then it expires.

Option 3
You can renew your plan, but that will mean you will change your current billing date to today. You can do this from your Tello online account or by texting "RENEW" to 800.
If you choose to renew your plan, 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 30 days from today.
There is no option to change your plan today for it to be effective starting from the next billing cycle.
