I was unable to download the "Lucky Wi-Fi Talk & Text" app to my cell from Google Play via my wi-fi. However, I was able to download the file to my lap top and transfer it to my "Sky_Pro_III" cell. Unfortunately I was unable to access to 4 digit implementation code with error msg Code: BE003 for which I cannot find any explanation. Called "Lucky" but they were of no help. I have the 50 minutes / no data plan. Wondering if I need a data plan to complete installation or if Cell is not an approved device. Any help appreciated, Thanks.
