I am currently looking at the 3G modules. Particularly for ones that are compatible with Nigerian telcos. For example the HL8518. I am designing a solution that requires a cellular connection. I was just wondering if anyone could inform me of the differences between the modules at sierra wireless and 3G USB dongles you can buy online. The HL8528 is priced at ~$40-50 dollars but 3G Huawei USB dongles are priced at $5-15 dollars. I am trying to justify the price difference between the two options. Any insights into the differences and similarities would be greatly appreciated.
