Been using Huawei E220 for around 1 month, I could say that this modem does its function well. No issue related to hardware. The installation process completed with auto-run in Windows Operating System, no need any installation CD, just plug the modem to any USB port and it will prompt you to start the software installation.
The connection is stable, however it depends on your network provider as well. in my home area, around Pangkalan Jati, Kalimalang. It could run very well for nights and days, without any need of reconnection.
This modem was launched back in 2006. Maximum speed is 3.6 Mbps, you could set this modem to use 3G only signal, or 3G prefered if you are not sure you will get a good reception of 3G signal.
Bought it for Rp.1.450.000 in a store at ITC Kuningan Jakarta, I am surprise to see this modem sold for Rp.1.250.000 at a small computer store in Palembang 
.
I use this modem along with Telkomsel Flash Unlimited Package which has virtually unlimited capacity but with limited maximum speed of 256Kbps (up to 3Gb per-month, before the speed is reduced to 64Kbps).
Connection of max 256Kbps is quite decent for me, allows me to check web mail, update anti virus, connect to my company VPN – Virtual Private Network, and do some downloads (never yet try to download big files though). However because the speed limitation of Telkom Flash unlimited package, I have never test the maximum speed of this modem.
I have tested this modem along with Telkomsel Flash in area of Kalimalang Jakarta (HSDPA connection – Very Good), Kuningan Jakarta (HSDPA connection – Very Good), Plaju – Palembang (HSDPA connection – not to good, some re-connection needed, sometime could not connect), Tuban – East Java (EDGE connection, but stable).
The whole body of this modem is plastics. There is no lock on the SIM card port, so you need to be careful not to drop this modem to the floor. It might spit out your SIM Card. Also don’t step on it, I believe it will break a part.
If you are a mobile person who need a notebook computer to work and be online, or you need a HSDPA modem which you could use on your home PC and notebook computer; and you just can’t rely on with your HSDPA smartphone for some reasons, I recommends Huawei E220.
