A machine-readable storage device storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• determining, at an portable electronic device, that the portable electronic device is out of network service coverage corresponding to a home network based at least in part on a first profile stored in a removable subscriber identity module (SIM) inserted in a socket of the portable electronic device, the first profile including information related to the home network and information related to a roaming network;
• establishing, using communication circuitry operatively coupled with the portable electronic device, a specified communication connection with the roaming network using the first profile based at least in part on the determining;
• transmitting a request for transmitting a second profile usable with a data service in a current location of the portable electronic device, via the specified communication connection with the roaming network;
• and
• receiving, in response to the request, the second profile via the specified communication connection, the receiving including storing the second profile in an embedded universal integrated circuit card (eUICC) included in the portable electronic device.
