I've noticed a trend of dual-SIM card mobile phones throughout Asia. Few days ago, I wrote an entry about Eliya I902 phone. Today, I present to you, the Samsung D880. This dual GSM SIM device looks like an exclusive offering for the Indonesia market. I've seen this phone on various billboard (see image) and print ads throughout Jakarta.
This phone is pretty cool in that both SIM numbers are active; there are two antenna bars on top representing each phone number. A very nice solution for business folks wanting to combine work and personal phones into one device.
For US consumers running on CDMA devices, take advantage of the Samsung W619 for some dual GSM+CDMA action.
