On my old Treo I had a PalmOS app and I am looking for the same information in Android market. The old app was made by www.aramis-inc.com which comes up now as some Japanese site. The app had 3 simple pick lists; Country dialing from, country dialing to, and mode. Where mode was direct dial, MCI, AT&T others... On choosing those it would tell you the dialing code. ie. presented 3 important pieces of information, the international access code it's 011 in US, but it's 0011 here in Australia and it varies around the world. I know you can puch in a + on the cell but I would normally be using a landline for these calls. Secondly tells you the country code for each location ie 1 for US, it's 61 for Aus. Thirdly showed the access number for each country for the major carriers. I work for a US co. so I have an MCI dialing card but I don't know all the access numbers in the various coutries I visit. Does anyone know an app that has this data?
