This phone "Nokia 225 4G (2024)" works with Sunrise because it is VoLTE-capable. The previous model "Nokia 225 4G" no longer worked because it only supported LTE.

The Nokia 225 4G (2024) has an alarm clock function, but no built-in calendar function. You can set an alarm via the Alarm menu, but to manage events, there is no dedicated calendar application.

My daughter has a subscription to the post office (salt). But it works with all providers

There is no hotspot function for the Nokia 225 4G (2024). The information in the official instructions and user manuals does not confirm the availability of this function. Instead, there are indications that the device does not offer Wi-Fi support, which further complicates its use as a hotspot.

If the unit was purchased in 2/2021, it is still under warranty. So the dealer should take care of the problem.

Hello. Yes

Unfortunately, our department responsible is not in a position to confirm this and I am very sorry about that.

Apparently there used to be a 225 with only one SIM slot. If it says dual SIM, then it will be dual SIM. I recently bought this phone (from another shop) for a similar price, and it has 2 SIM slots (nano-SIM) and a micro-SD slot.

No, unfortunately you cannot install Whatsapp.

Hi It, until now I have never used this function and therefore cannot confirm that it works. I have other gadgets to access the internet. Sorry.

According to our information, this is not possible.
