This means there are no contexts. 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.

The SIM PIN credentials are separate from GPRS context credentials.
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.

Correct, oFono persists the information in /var/lib/ofono. You only
need to run create-internet-context if your settings are wrong.

This all sounds correct. Btw, you can also use
test/process-context-settings to do the above. It should even do the
DHCP / static assignment correctly.

If you are using an AT&T GoPhone SIM then likely you're limited to
WAP-only network, not a real internet connection. The easy way to tell
is to run
test/create-internet-context "isp.cingular"
And then try to activate the context.
