So route assignment, DNS entry assignment, etc are not done by oFono. oFono only brings up the interface and assigns the local IPv4 address.

What APN are you using, the WAP-only APN or something that allows actual internet connections?

For MBM they show up after you run online-modem. Assuming a brand new, virgin device, oFono runs context provisioning using mobile-broadband-provider-info. If you are lucky, the context will be configured automagically and the list-contexts output will look something like this: denkenz@localhost ~/ofono-master $ test/list-contexts [ /mbm_0 ] [ /mbm_0/context1 ] Username = Protocol = ip Name = Internet Settings = { } IPv6.Settings = { } Active = 0 AccessPointName = wap.cingular Password = Type = internet

The settings are then persisted in /var/lib/ofono/<your sim card's imsi>

If provisioning fails, oFono creates a default, empty context. It can be recognized by an empty APN. In theory activating an empty APN should fail. You then need to use create-internet-context to set the settings manually. For AT&T the WAP-only APN is wap.cingular, and the data APN is isp.cingular I believe.

Essentially the SIM PIN locks the SIM card, so the modem cannot read what is on it until the PIN is entered. Once the access to the SIM card is allowed, we can 'dial up' to the network. Think of the APN details as old style dial-up modem credentials. E.g. APN is the phone number, and the username and password are self-explanatory. > If I'm understanding this correctly, there exists one context for the > mbm_0 modem after I ran create-internet-context, and it is no longer > necessary to run create-internet-context again (assuming it was created > correctly). > Correct, oFono persists the information in /var/lib/ofono.

It should even do the DHCP / static assignment correctly. >>> # ./list-modems >>> [ /mbm_0 ] >>> Features = gprs net cbs ussd gps sms stk rat sim >>> Emergency = 0 >>> Powered = 1 >>> Lockdown = 0 >>> Interfaces = org.ofono.ConnectionManager org.ofono.NetworkRegistration org.ofono.CellBroadcast org.ofono.SupplementaryServices org.ofono.LocationReporting org.ofono.SmartMessaging org.ofono.PushNotification org.ofono.MessageManager org.ofono.SimToolkit org.ofono.RadioSettings org.ofono.SimManager >>> Online = 1 >>> Model = F5521gw >>> Revision = R2A07(R2A07) >>> Type = hardware >>> Serial = 356215040140315 >>> Manufacturer = Ericsson >>> [ org.ofono.ConnectionManager ] >>> Powered = 1 >>> Attached = 1 >>> Bearer = none >>> Suspended = 0 >>> RoamingAllowed = 0 >>> [ org.ofono.NetworkRegistration ] >>> Status = registered >>> Strength = 80 >>> Name = AT&T >>> LocationAreaCode = 33998 >>> Mode = auto-only >>> MobileCountryCode = 310 >>> Technology = hspa >>> CellId = 13805302 >>> MobileNetworkCode = 410 >> >> I see you're on AT&T.

The easy way to tell is to run test/create-internet-context "isp.cingular" And then try to activate the context.

If name resolution is working, doesn't this suggest that you get packets to the network?

His phone reported an "EDGE" connection and successfully, albeit > SLOWLY, displayed web pages. You are using your pre-paid SIM in this phone correct? Was it an older feature-phone type device? If so, then I suspect the phone is using the WAP browser, not a regular internet connection. That is what WAP gateway is for, to convert regular HTML web pages into an 'optimized' binary format on slow (think 10 years ago) networks. > > So this suggests to me that the SIM can do IP and not just WAP.

Unfortunately US carriers don't really understand that it is useful to have actual data allowances on prepaid plans ;)
