### eUICC: How to send raw APDUs from EHS5 to eUICC SIM ### | Telit Cinterion IoT Developer Community

Hello,
I have a eUICC SIM containing two profiles and I have to test the switch between the profiles.
I am using an EHS5-E Eval setup and I have been given two magic APDU commands which
evoke the profile switch. I wonder which is the right AT command to directly send raw APDUs
given as hex string from host MCU via the EHS5-E modem to the eUICC. Can I use the SIM Applicaton Toolkit somehow for this ?
thanx and best regards Oliver
Hi Olivier,
For this you should use AT+CSIM command. The detailed description you may find in AT specyfication.
Best regards,
