Familiar fixed-line operation, clear HD voice quality and flexible usage via mobile networks – powered by modern 4G/LTE technology (VoLTE).
With the new Gigaset COMFORT 600 SIM, the German communications specialist expands its portfolio with a modern LTE telephone that combines the familiar user experience of a classic landline handset with the flexibility of mobile connectivity. The device is designed for users who want to make calls independently of a landline connection – with familiar handling, excellent voice quality and maximum flexibility.
Making calls without a landline – simply via LTE
The COMFORT 600 SIM uses Voice over LTE (VoLTE) for brilliant HD voice quality, stable connections and fast call setup times. A single nano-SIM card is all that’s needed to start using the phone – no internet router or landline required. Wherever mobile coverage is available, the COMFORT 600 SIM is ready to use.
Fixed-line comfort meets mobile flexibility
While various SIM-based phones exist on the market, they are generally simple in design and lack the intuitive operation of classic cordless phones.
Gigaset intentionally takes a different approach:
A large, high-contrast 2.4" TFT colour display, excellent HD voice quality and an intuitive menu structure featuring clear icons and Gigaset’s proven user logic create a comfortable and instantly familiar user experience – no matter the location or whether a landline is available.
Ergonomic design – slim, lightweight and comfortable to hold
With its slim 18 mm profile and ergonomically curved back, the COMFORT 600 SIM sits comfortably in the hand. Its high-quality feel makes it ideal for everyday use – whether at home, in a holiday property or in small business environments.
Flexible use: at home, in holiday homes, campervans or mobile businesses
The COMFORT 600 SIM is ideal for rural areas without or with decommissioned landline infrastructure, holiday homes and second residences, mobile living concepts such as campervans or tiny houses, senior care facilities and hospitals, as well as small businesses, studios and shops with changing locations. Wherever mobile coverage is available, calling remains reliable and clear.
