we have released today 2 new test software versions in the test software.
V27 Sasha+ is an improved software version that should work better than V27 in witch we solved some communication bugs and most important the SMS bug affecting SIM type of cards (USIM type was working). V27 is also designed to let 2G data work but this does not mean will work with all simcards, only with some. The use of iRose is requires to get stable long time signal.
V27 Sasha- is the same as V27 but with SMS bug solved. No data is enabled in this update as it was not enabled in V27.
Please test this 2 updates so we can choose the best one to replace the existing V27 in general release software and solve the issues some customers are having with SMS.
