After plan activation, you can request to switch your Google Fi plan in the Google Fi app  or at fi.google.com. Before you make changes, compare plan details like data allowances, hotspot limits, and international features. Most plan changes take effect at the start of your next billing cycle.
Switch your plan
- Sign in to your account on the Google Fi app or at fi.google.com. 
- Tap Manage plan.
- Under "Actions," tap Switch plan.
- Follow the instructions.
You can choose to switch plans once a month. After you change plans, at the top of your account, you and any group members get a notification. The notification says when the new plan starts.
If you change from Unlimited Premium to Flexible, Unlimited Standard, or Unlimited Essentials you can lose your Google One benefits after 7 days.
To keep your Google One benefits:
- Set up payment for Google One.
- After you switch your Google Fi plan, in the pop-up notification, click the link.
Cancel a scheduled switch
Important: You can schedule a plan switch for the start of your next billing cycle. If you do so, you can cancel the switch and stay on your current plan type any time before the start of your next billing cycle.
- Sign in to your account on the Google Fi app or at fi.google.com. 
- Tap Manage plan.
- At the top of the "Account" section, find a notification of your scheduled plan switch.
- Tap Cancel switch.
Manage your group plan
When you’re in a group plan, specific rules apply for member management and plan changes.
- Only the group owner can make changes: They can switch the plan type for the entire group. They can also add or remove members.
- All members share the same plan: Members of the group must be on the same plan, like all are on Unlimited Standard. You can’t mix plans within a single group.
    - If the group owner switches the plan, all members are moved to the new plan.
 
- Members who want a different plan: If a member wants a different plan, they must first leave the group plan. After they leave, they can switch to their preferred plan as an individual.
- Group ownership can’t be transferred: To change the group owner, the current group needs to disband. All members need to leave, and the new owner can then create a new group plan and invite others to join.
To add a member :
- Open the Google Fi app or go to fi.google.com.
- Go to Manage plan.
- Select Add a member.
- To send an invitation, enter the person's email address.
Manage your bill changes after changing plans
If you change from Flexible to Unlimited Essentials, Unlimited Standard, or Unlimited Premium, your first bill can be higher than usual.
Your bill includes:
- Charge for the next month of Unlimited Premium plan that prepaid owners and members pay.
- A $10 USD per GB charge for postpaid owners and members who used data in the last bill cycle.
- Post pay for extra services you used in the last bill. Extra services can include:
    - International calls
- Request to get your data back to full speed
- Prorated costs for new members
 
For example:
You just switched from the Flexible plan to an individual Unlimited Standard plan. In your last month, you used $20 USD of data on your Flexible plan. Your next bill includes:
- $20 USD for data on your Flexible plan, which you postpay.
- $50 USD for your Unlimited Standard plan, which you prepay.
To find your current billing cycle:
- Sign in to your account on the Google Fi app or at fi.google.com. 
- At the top of your screen, find the notification "Cycle ends X days."
