Bug 793111 introduced PLMN entries reading, taking as argument the number of entries to read. According to the current codebase, I can see the argument is tlvLen/6. As far as I remember, I had the same tlvLen value, but did divide it by 3. I see no justification but the /6, and running tests on my system (Free Mobile SIM card, Nexus S), I get: with /6: $ adb logcat | egrep -i "readPLMN" I/Gecko ( 77): RIL Worker: readPLMNEntries: PLMN entries length = 1 I/Gecko ( 77): RIL Worker: readPLMNEntries: Reading PLMN entry: [0]: '2,248,16' I/Gecko ( 77): RIL Worker: readPLMNEntries: PLMN = 208, 1 with /3: $ adb logcat | egrep -i "readPLMN" I/Gecko ( 77): RIL Worker: readPLMNEntries: PLMN entries length = 2 I/Gecko ( 77): RIL Worker: readPLMNEntries: Reading PLMN entry: [0]: '2,248,16' I/Gecko ( 77): RIL Worker: readPLMNEntries: PLMN = 208, 1 I/Gecko ( 77): RIL Worker: readPLMNEntries: Reading PLMN entry: [1]: '2,248,32' I/Gecko ( 77): RIL Worker: readPLMNEntries: PLMN = 208, 2 with /2: $ adb logcat | egrep -i "readPLMN" I/Gecko ( 77): RIL Worker: readPLMNEntries: PLMN entries length = 2 I/Gecko ( 77): RIL Worker: readPLMNEntries: Reading PLMN entry: [0]: '2,248,16' I/Gecko ( 77): RIL Worker: readPLMNEntries: PLMN = 208, 1 I/Gecko ( 77): RIL Worker: readPLMNEntries: Reading PLMN entry: [1]: '2,248,32' I/Gecko ( 77): RIL Worker: readPLMNEntries: PLMN = 208, 2 I/Gecko ( 77): RIL Worker: readPLMNEntries: Reading PLMN entry: [2]: '255,255,255' Do you have spec/link suggesting/confirming the /6 value ? All I can find is ETSI spec, TS 131.102, section 4.2.66 which states: "Note: the length is 3*n bytes, where n denotes the number of PLMN entries. The length can be coded on one or more bytes."
And for your information, 20801 and 20802 are other valid assigned PLMN for Orange network in France, which Free is roaming on.
Attached patch Trivial fix (obsolete) (deleted) — Splinter Review
Works well on Free Mobile USIM card, and should comply to legacy SIM specifications (but no way for me to test).
20801 is main Orange network identifier, and 20802 is a special one for zones with low coverage and specific multi-operator network to cover at lower cost.
