Hi All

I want to test the module in Japan.  
But I meet a question.  
In the Japan, the “SIM free” is running in May this year.  
It means we can use the MC7304 or MC7330 on the other carrier(NTT docomo , softbank, or KDDI…etc).  
Is it right?

1. May I use the Japan sim( any carrier if band support ) put into MC7304 and connect to cell? the get Ip address?
2. the MC7330 FW is sim lock on NTT-docomo, does it have release newest FW for sim free?
3. or someone have the experience?

Many thanks.

hi,  
you can try with generic firmware… it should support all carriers…

Thanks,

Hey ,

I have here with me a MC7330 with the following firmware: “SWI9X15C\_05.05.26.00 r21289 carmd-fwbuild1 2014/04/02 18:24:1”

For some reason it looks like as if the device is locked to one operator, as the original reported stated with:

> [@](#):

> the MC7330 FW is sim lock on NTT-docomo

The “Initiate Network Register” QMI NAS command is giving me “FAILURE: UimUninitialized”; and when I check the status of the SIM card with QMI UIM “Get Card Status” command it says that the “usim” application requires the “gw-network” personalization code:

```auto
>>>>>> TLV:
>>>>>> type = "Card Status" (0x10)
>>>>>> length = 45
>>>>>> value = 00:00:FF:FF:FF:FF:FF:FF:01:01:00:00:00:00:01:02:04:03:00:FF:20:10:A0:00:00:00:87:10:02:FF:34:FF:01:89:05:06:00:FF:00:03:03:0A:01:03:0A
>>>>>> translated = [index_gw_primary = '0' index_1x_primary = '65535' index_gw_secondary_ = '65535' index_1x_secondary = '65535' cards = '{ [0] = '[card_state = 'present' upin_state = 'not-initialized' upin_retries = '0' upuk_retries = '0' error_code = 'unknown' applications = '{ [0] = '[type = 'usim' state = 'check-personalization-state' personalization_state = 'code-required' personalization_feature = 'gw-network' personalization_retries = '255' personalization_unblock_retries = '32' application_identifier_value = '{ [0] = '160 ' [1] = '0 ' [2] = '0 ' [3] = '0 ' [4] = '135 ' [5] = '16 ' [6] = '2 ' [7] = '255 ' [8] = '52 ' [9] = '255 ' [10] = '1 ' [11] = '137 ' [12] = '5 ' [13] = '6 ' [14] = '0 ' [15] = '255 '}' upin_replaces_pin1 = 'no' pin1_state = 'disabled' pin1_retries = '3' puk1_retries = '10' pin2_state = 'enabled-not-verified' pin2_retries = '3' puk2_retries = '10' ] '}' ] '}' ]
```

So, is that so? is this firmware locked to NTT Docomo? And if it isn’t, why could it be asking for the gw-network personalization code?

Thanks.
