Work down this list: (1) the StateLine line is turned On in your SIM settings; (2) Data Roaming is ON for the StateLine line — outside the USA the line roams, so this one is required; (3) toggle Airplane Mode on for 10 seconds, then off; (4) restart the phone. Most "no signal" cases are roaming being off.
Your number is assigned when the line first connects to a network. Install the eSIM, turn the line on with roaming on, wait a few minutes in an area with coverage, then refresh your delivery page or dashboard — the number appears there the moment the line connects.
Check your remaining basket on your dashboard — when a plan's texts or minutes run out, that part of the line stops until you top up or buy a new line. Also check the line shows as connected (see "No signal" above). Calls connect inside the USA; outside it, texts and data are what the line carries — in our own tests from Nigeria, calls did not connect.
Don't delete anything and don't keep retrying blindly. Take a screenshot of the exact error and email it to support@getstateline.com with your phone model — we'll walk you through the manual activation-code route.
Straight answer: a deleted eSIM profile can't be brought back, by us or anyone. The line is gone with it. A new plan gives you a new line and a new number. If you only turned the line off, that's different — turn it back on in SIM settings and everything returns.
Email support@getstateline.com from the email you bought with, with your phone model and a screenshot of what you see. We'll get you connected.
