The internal storage of the Samsung Galaxy S9 can now be increased by up to 400GB via MicroSD card. That’s an increase from 256GB from the Galaxy S8.
A version also exists with a Hybrid Dual SIM that allows you to use two SIMS. A local SIM when you’re on vacation and keep your home number connected or use separate work and personal numbers on the same phone. When using two SIM cards the MicroSD card can’t be used.
It now looks like this Hybrid Dual SIM option is available for users in Germany for the first time. SH Telekommunikation Deutschland GmbH, a provider of independent mobile phone contracts and mobile devices is listing the Dual SIM variant through its website here.
Thanks to Marco for the tip.
