network search takes long time after flight-mode or network sim change

Hi, recently i have used the xperia-10 with SFOS while traveling and had to change the network sim quite often cause of bad coverage. I used a vodafone sim1 and a telekom (congstar) sim2 in germany, both with LTE. When changing the network connection from sim1 to sim2 - both had been "status registerted" with umts or lte - status from sim-scout app - sim2 goes "offline" and network on sim2 is "searching". Same thing the other way-around when switching from sim2 to sim1. The "connecting back" to the network takes around 20secs to 2 minutes, even with a good signal afterwards.

Is this "normal" that the device loses the network, when changing the internet-connection to the other sim?

I also used the flight-mode quite often - saving battery while hiking - and when disabling the flight mode, searching for a network also takes the same amount of time. It does not matter if I have perfect 4G on both sim cards afterwards, I just counted 1:30mins to connect both sims.

Does your xperia-10 also need this long to register to a network after flight mode/reboot?

I can confirm the described behaviour (Xperia 10 plus in my case), and have just created a service request at Jolla support.

This is also an issue on my Jolla 1 phone, but already since many Sailfish versions.

Similar for me, network handling and handover on the X10 is very unreliable and slow since SF3.3

Jolla support responded to my Request #36979 very quickly:

There is nothing we can do at the moment, but our next SW release 3.4.0 will have fixes on various areas so once it is is available, please update your device and see if it works better. You can continue commenting on together.jolla.com but we will close this ticket now.

So let's hope for a fix in SFOS 3.4.

". . . will have fixes on various areas" - how non-specific : /
