The MCC and MNC digits from 1 to 5/6 (red and yellow on the images) show the network. Subsets and regional operators can be calculated by last 9 or 8 digits (blue and yellow) aka MSIN. Where is IMSI stored locally: all the IMSI bundles are stored in /System/Library/Carrier Bundles. For instance, if you use AT&T SIM card, his name will be ATT_US.bundle var/mobile/Library/Carrier Bundles. The iOS will also create shortcut to that folder which will look like this: var/mobile/Library/Carrier Bundle.bundle. To find your iPhone's IMSI number you can use two methods. One is to check IMSI by running minicom in your terminal and typing in: AT+CIMI then press enter and you'll see your IMSI number. The second method fits SAM unlock better. Run installed SAM app on your iPhone and go to More Information->IMSI under SIM Details submenu. You'll see a 15-digit IMSI code that corresponds to your SIM card. That's it.IMPORTANT! How to find your carrier within IMSI:
- When you have that number just check iPhone operator
- Type it in to the field called Enter IMSI number
- It will show your SIM carrier's country, operator, your MCC and MNC
- Country - 234- UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND
- Carrier - 15 - VODAFONE LTD
