How to make a telephone call from Java Me
Article Metadata
Making a telephone call from Java Me is not possible still. There is an API called JSR 253 called Mobile Telephony API but this is not supported by any of the mobile phone right now. No mobile phone manufacturer has even mentioned that whether they would include that in their mobiles in future or not.
As far as current scenario is concerned the only way to make calls through Java ME is through
platformRequest("tel:put the mobile number here")


Some Motorola products support it. One of the product is Motorola A780. It is supporting Telephony API. So you can make call and even you can block call in that product. But unfortunately no Nokia product is supporting it yet. We hope in the future it is available.
For reference we can use this discussion.
