- For Android Devices:
- Go to your phone’s “Settings” menu.

2. Use USSD Codes for SIM Card Information
Another simple way to retrieve SIM card details is by dialing a specific USSD (Unstructured Supplementary Service Data) code, depending on your carrier. These codes are unique to each carrier and allow you to check your balance, data usage, and other SIM-related information.
Here are some popular USSD codes:

- Verizon (US): Dial *611 or *#DATA to check your data usage.
- Vodafone (UK): Dial *#100# to check your balance and SIM details.
Note that these codes may vary based on your carrier and country, so it’s a good idea to check with your service provider for the correct USSD code for your needs.
3. Contact Your Carrier for Assistance
If you need more detailed information about your SIM card, or if the previous methods don’t provide what you’re looking for, you can always contact your carrier. Most carriers have customer service teams that can help you with SIM card information lookup.
Carrier customer service can assist with:
