I wanted to open up a thread specifically for issues relating to projects using the Huawei E303 Cellular Modem. This modem is currently in our store and is being distributed with the Raspberry Pi and BeagleBone KS kits.
One thing that makes dealing with this modem tricky is that there are a ton of them out there for sale and even though the model number and hardware revision may be exactly the same, differences in firmware can create differences with connecting to different networks.
We’ve just learned this the hard way as it seems like the modems we have in our store don’t seem to work on 3G in the US (or at least here in Chicago) and can only get a 2G connection. We know that the hardware can do it because we have another E303 here with Claro firmware on it that can get 3G in the US. Not a huge deal as our data plans aren’t exactly designed for watching Youtube anyway, but I’m sure we’d all like a faster connection.
I’m looking into finding a firmware that solves this problem but if anyone on here has already found one that works, please pass it along.
