MKR GSM 1400 problem with GSM.begin() in sync and async mode

Hi All

There are a few similar issues but none of them resolved my problems.

In Sync Mode:
Using the standard library code for initializing the GSM network the
GsmAccess.begin(PINNUMBER, true,true) (That is sync mode) works well and connects within a few seconds every time.

If the GSM network is not available the GsmAccess.begin function never returns a value. This means that the whole program waits.

In Async mode:
If GsmAccess.begin(PINNUMBER, true,false) (That is async mode) is used while no network is available together with GSMAccess.ready() the ready functions returns "busy". If you add a time limit then you can let your program continues after the time limit is reached.
If however a network is available, in async mode it takes about 30 to 40 seconds to connect to the network as apposed to the 2 or 3 seconds in sync mode.

Is there a way to reduce this 30-40 seconds?

Many thanks
