Distinguish profile installation from the plan’s validity start; the provider sets the rules.
Before installation
Save instructions, account access and a support contact.
Configuration
Set the data line and roaming requirements according to the provider’s instructions.
Test
Test without Wi-Fi; do not delete a faulty profile before checking reinstallation options.
Work in a verifiable sequence
Gather the required information, perform the action, then verify the outcome. Do not automatically repeat a payment or submission when the first attempt’s status is unknown. Keep confirmation and the case reference somewhere independent of a device or channel that could become unavailable.
