The magenta operator has entered the fight for family budgets. T-Mobile has just launched a limited-time promotion that slashes the price of a tariff with 5 GB of data to 335 crowns per month. Under normal circumstances, you would pay 485 crowns for the same package, so you save a full one hundred and fifty crowns.

The tariff is primarily intended as a second or additional SIM card for family members. In addition to 5 GB of fast data, it includes 150 free minutes and the same number of SMS messages. While this isn’t a showstopper, it’s more than enough for children or grandparents who call via WhatsApp and message on Messenger.

Internet that never ends (but slows down a lot)

An interesting feature of the tariff is the service Always Online. When you exhaust your 5 GB, the internet doesn’t stop completely – it just brutally slows down to 256 kb/s. This is a speed at which you can forget about YouTube or Instagram Stories, but you can still send a message on WhatsApp, check your banking app, or look up a timetable.

It’s essentially a safety net – you’ll never be completely offline. For parents who want to ensure their children are always reachable, this feature can be crucial. The service is activated for free in the My T-Mobile app and is always valid until the end of the billing period.

No commitments, no penalties

T-Mobile boasts that the tariff works without any commitments. You can change it every month according to current needs or even cancel it completely if it no longer suits you.

The package also includes Secure Mobile Internet, designed to protect you from fraudulent websites and phishing attacks. In an age when even grandmothers pay by card via phone, having such insurance is not a bad idea. Naturally, there’s the option to transfer your existing number – whether you’re switching from a prepaid card or a competitor.

Beware of the time limit

The catch is that the promotion is valid only until September 30, 2025. The offer is available only for new activations, transfers from T-Mobile prepaid cards, or new customers from competitors. Existing postpaid customers cannot benefit, which is a shame. You can get it on the operator’s official website.

Activation with eSIM truly takes only a few minutes – you download the app, fill in your details, and within fifteen minutes, you have a functional number. A classic plastic SIM will be delivered by courier or can be picked up at a store.

If you’re looking for a tariff for another family member or seeking an affordable, no-commitment option, it makes sense to check out T-Mobile’s offer.
