Note- You can further confirm on the SIM card’s functionality by testing it in a different phone. If by chance your SIM is not working or if you have noticed damage on it, you should contact your service provider for a replacement of the same.

While the same issue may show up for an Android phone too, the settings or interface of the iPhone might not be known to the new or inexperienced users.
