Can I use a OneSimCard enabled phone in Japan, South Korea, Myanmar and others?
All OneSimCard international SIM cards work in Australia, Japan, South Korea, Taiwan, Myanmar, Singapore and other couuntries where 2G networks no longer available. These countries use 3G/WCDMA networks, so only phones with the specific 3G/WCDMA/HSDPA/UMTS 2100 frequency will work in these countries. Most modern smart phones have this option today including all iPhones. You should check your phone specification to make sure your phone has this 3G band,
OneSimCard offers cell phones with the necessary 3G band for Japan and South Korea that also work in every other country where we provide service:
Is there a way to send a SMS to a short code number?
Having an EU phone number, the SIM card does not offer SMS service to short code numbersI was charged a large amount for mobile data service even though I barely used data, what happened?
Each mobile data session is charged for a minimum of 10kB usage. Even if you check just one 3k email you will be charged for 10kB of usage. In some countries this can be over 30c per session, however in Europe and elsewhere it can be as little as 1c. Check all rates.
Please note: Some phones, like iPhones and other smartphones, can access data without you even knowing it if you have data enabled. We strongly recommend checking the settings on your phone or disabling GPRS from your OneSimCard account if you will not be needing data service. By default, all SIM cards are pre-programmed with GPRS data service disabled.
