Dear support,

Yesterday I received my new Speedport Smart 4 + 5G empfänger (from a Speedport Pro Plus with LTE hybrid).

However the 5G / LTE connection is not active, only DSL is working.

I tried several things without any success:

- Smart 4 + 5G Empfänger with old LTE contract SIM card > 5G / LTE not active only DSL working

- Smart 4 + 5G Empfänger with new received 5G SIM card > 5G / LTE not active only DSL working

- "Old" Speedport Pro Plus Hybrid with old SIM card > DSL + Hybrid working

- "Old" Speedport Pro Plus Hybrid with new received 5G SIM card > Hybrid not working only DSL

- several reboot of empfänger and smart 4..

I conclude that I should have the new 5G SIM card defect or to be activated?

I suppose that only the new SIM card received is recognized by the empfänger.

Thank you !

Jordan
