Can I keep using my services after I submit the cancellation request?

Yes. Your services remain fully active throughout the 30-day notice period from the date T-Mobile receives your request. You will be billed for usage during this period on your final invoice.

Are there any cancellation fees?

No penalty fees apply if you have been a customer for at least 3 months (Czech law since April 1, 2020). If you cancel before 3 months, T-Mobile may charge up to 1/20 of your remaining monthly fees. Separately, if you received a subsidised device, you must repay the remaining value of the device regardless of contract length.

Can I keep my phone number when I leave?

Yes. Request your OKU (Ověřovací Kód Účastníka) from a T-Mobile store or by calling 800 73 73 73 (free call). Provide it to your new operator — they will handle the number port and the contract cancellation on your behalf. Porting typically takes 5–8 business days.

Can I reactivate my service after cancelling?

You can withdraw your cancellation request before the 30-day notice period expires by calling 800 73 73 73. After the service is fully terminated, you would need to sign a new contract.

Will I get a refund for unused prepaid credit or advance payments?

Prepaid credit (kredit) is generally non-refundable upon cancellation. For postpaid plans, you are billed only for actual usage through the termination date; any advance billing is prorated and credited on the final invoice.

What happens to my data and account after cancellation?

Access to 'Moje T-Mobile' (My T-Mobile) self-service portal is terminated when the service ends. T-Mobile retains account and billing data as required by Czech law (typically 10 years for invoicing records). Your number is released and may be reassigned after a regulatory hold period.

Review your contract terms

Go to https://www.t-mobile.cz/podpora/smlouva/jak-opustit-t-mobile and review your contract type. Check if you have a fixed-term commitment and whether you received a subsidised device, as you may need to repay the remaining device value. If you have been a customer for 3+ months, no penalty applies for early termination.

Download the termination form

Visit https://www.t-mobile.cz/ke-stazeni and download the contract termination form ('Žádost o ukončení smlouvy'). Alternatively, you can write a free-form written request or use the online contact form at https://www.t-mobile.cz/podpora/kontaktujte-nas — choose topic 'Smlouva a účet' then 'Ukončení smlouvy'.

Complete the termination request

Fill in all required details: your full name (jméno majitele smlouvy), the phone number or service ID to terminate (ukončované telefonní číslo nebo číslo služby), whether it is an early termination (předčasné ukončení), and your handwritten signature (vlastnoruční podpis). For the online contact form, type these details in the message body.

Submit the request

Choose a submission method: (A) Online — submit via the contact form at https://www.t-mobile.cz/podpora/kontaktujte-nas; (B) In-person — bring the signed form to any T-Mobile prodejna (store); (C) By post — mail to: T-Mobile a.s., Tomíčkova 2144/1, 148 00 Praha 4. Keep a copy or confirmation number.

30-day notice period begins

The 30-day notice period ('výpovědní doba') starts from the date T-Mobile receives your request ('ode dne doručení výpovědi'). Your services remain active during this period. For fixed-term contracts still within commitment, the contract ends either at the commitment end date or after 30 days if early termination was requested.

Receive final bill

Your last invoice ('Poslední Vyúčtování') arrives on your normal billing date, with charges prorated through the termination date. If you had a subsidised device, the remaining device cost is included. If porting your number to a new provider, obtain your OKU code (14-digit Ověřovací Kód Účastníka) from customer service 800 73 73 73 — the new provider handles the rest.
