1. The offer
Sign up to an eligible Zable Mobile capped data plan, port in your existing mobile number, and enter the promo code provided to you at checkout, and you won't be charged for your first monthly billing cycle. Your normal monthly plan charge applies from your second billing cycle onwards.
2. Offer period
The offer is available for a limited time. We may change or withdraw it at any time without notice. Withdrawing the offer won't affect anyone who has already successfully redeemed it.
3. Who can take part
To qualify, you must:
Be a UK resident aged 18 or over.
Have a Zable account and subscribe to a new eligible capped plan (see section 4). This includes existing Zable app and card customers.
Not already have an active Zable Mobile plan at the time you sign up.
Transfer (port) an existing mobile number to Zable Mobile as part of sign-up. Sign-ups that take a new number rather than porting one in do not qualify.
Enter the promo code provided to you as part of this offer at checkout.
The offer is limited to one free month per customer. It can't be combined with any other Zable Mobile offer or Zable membership discount, and has no cash alternative.
4. Eligible plans
The offer applies to Zable Mobile's capped data plans only:
3GB
5GB
10GB
20GB
The offer does not apply to the unlimited data plan.
5. How to claim
Choose an eligible capped plan in the Zable app.
Select the option to keep your existing number and provide your PAC (porting authorisation) code.
Enter the promo code provided to you as part of this offer at checkout.
Complete sign-up. The offer is applied once your number has successfully ported to Zable Mobile.
If your number port is not completed successfully, the free month may not apply.
6. What happens after the free month
Your plan is a rolling monthly plan. Your standard monthly charge applies from your second billing cycle and every month after that.
Current monthly prices are shown in the Zable app before you sign up.
You can cancel at any time in the Zable app. If you cancel during your free month, your plan and service will end and no charge applies. Cancelling does not entitle you to any credit or payment.
7. General
We may amend these terms where we reasonably need to (for example, to reflect changes in the law or how the offer works). The current version will always be available at this page.
We may withdraw the offer from anyone we reasonably believe has abused it or provided false information.
Standard Zable Mobile terms apply to your plan and service alongside these terms. Where these offer terms conflict with the standard terms, these offer terms apply to the free-month promotion only.
These terms are governed by the laws of England and Wales.
