I answered over e-Mail but have not got any response, Maybe I don't know how this community works but it is now already 5 days ago. This what I wrote:
The IMEI of the phone is the joint of all the numbers that I supply already on the e-mail but I will give it you again.
Sorry to hear. I used the private message function. Send message to moderator_team. You may be experiencing an activation problem. I'm a little confused about what that website is, doesn't look to be legit.
@Henk You have posted to an old thread. In future you will have more assurance of help by creating your own topic on the forum (which I have done for you today), or sending a private message directly to the moderators.
Because this is a public forum never post personal info; your IMEI number has been deleted.
What is make/model of your phone?
What message do you see on the phone when you reboot with the SIM installed?
Though it does sound like a provisioning error that will need the moderators. By email did you mean private message? If not, click this: message to moderators to send a private message to the moderator team with your phone number, account PIN, and an explanation. Moderator hours are: Monday - Friday 9AM (ET) - 9PM (ET); Saturday - Sunday 9AM (ET) - 7:00PM (ET).
@Henk, sorry to hear that you have not heard back from the moderators for 5 days, they are totally pretty quick.
If your phone supports Public Mobile's network frequencies and you're getting the "No Service" error, it probably means something went wrong during the activation process. That means you will have to reach out to the moderators for help, send them another message following the instructions that @Luddite provided above.
