Again bad news from Telogic, the company who provides German numbers and roaming service in Germany for SIM&WEB and its sister brands:
teltarif.de reports that after Deutsche Telekom cut off the leased links for Telogic's core network (which have been restored in the meantime) now eplus, the MNO whose radio access network Telogic uses, has banned Telogic IMSIs from their network due to unpaid bills. That means Telogic customers cannot register on any network anymore. Afaik SIM&WEB and their sister brands have deployed an OTA update for their SIM cards so when staying in Germany their SIM cards do not any longer use the Telogic IMSI for roaming but the "global" IMSI from Mobilkom Liechtenstein (which involves higher prices for Germany). Despite by this roaming service has been restored Telogic's precarious situation means SIM&WEB customers' German numbers are still at risk since Telogic may again go bust due to the fact that they do not have a radio asccess network and so no coverage in Germany which will very likely convert into a dangerous customer churn rate.
