Wahhhhhhhhhhh
Ok first. I damn relieved to see this post.
Hahahaha.
I thought my phone got problems!! I'm using a k618i for 6 months dy. Was thinking, tomoro wanna go Lowyat, go back to the shop who sell me, to ask them to mend.
Same lo, after 10 minutes, or even worse, 1 or 2 minutes, will show inactive sim again! Happen the whole day already. Want to cry.. Keep taking the sim in and out, clean the sim, clean the sim detector whatever, also cannot!
Anyway, I read from another source, that this problem can be connected to 3G.
So what I've tried to do is, i go to the connectivity (for Sony Ericsson), select mobile networks, then under GSM/3G networks, you select GSM only... don't select GSM and 3G..
Once you select, from inactive sim, can straight become active again (im using Maxis postpaid)... no need to even restart the phone..then can immediately send sms and call out also. Yay!
This has worked for me so far. For the last 30 mins. Hahaha. Will post again if this fails later.
Hope it helps! And hopefully, maxis will solve the problem fast!! Grrr. Want to make video calls also cannot

Btw I think they cheat la, 1 or 2 hours. Whole day already ok! Around 10 hours so far. Hm!
