Sim Card Question

I searched the forum and a little confused about what phone can use the sim card sells in Japan. We are going to stay in Japan for 15 days.

We have two unlocked AT&T phones and would like to find out if the two phones can use the Japanese SIM card:

1) LG Quantum C900 (quad-band GSM device with WCDMA modes for international use).

2) LG GT550 Encore (It runs on the 850/900/1800/1900 MHz GSM/GPRS/EDGE frequencies as well as AT&T's dual-band 3G network (850/1900 MHz; HSDPA/UMTS)

Thank you very much for your advice.

1) insufficient information.

2) No

You need 2100Mhz 3G (UMTS/HSDPA)

I have also been researching for better deals regarding mobile access. I've some across two sites that seem ok. I've never tried them yet. Though i plan to when I visit next month.



There is phone/mobile wifi rental at the airports but the prices are quite high.

Thank you all for the response. We are going to stay in HK for 10 days before Japan. It might be better to get HK rechargable sim card and use the phone in Japan. Just pay roaming fee and Japan rate. Please let me know if you don't think that will work.

Lala, we are going at the end of October. Please update me if you possible about your mobile access in Japan.
