Even I use to use callontime.com. Its not bad. I use to use "Smart Asia" which is the best one I guess to Nepal. But its kind of expensive like 27 cents per min. So, after using this tel3call.com, I am kind of happy. I can call either few mins or long call, I will get charged for the time I use and there is no hassle of buying new card everytime. I can call Nepal whenever I want with my cell phone. Above all, I found this tel3call.com more convenient. However, I am still looking for one with better price.
