Multi-IMSI means there are at least two IMSIs on the same SIM card, which allows the customer to get coverage of ‘both worlds’, which means roaming is possible in all networks, which either do have an roaming agreement based on 1NCE standard IMSI or based on CTG IMSI. The China+ SIM itself only provides additionally NB-IoT and 4G coverage via the CTG network in Mainland China and 4G coverage in Macao.
