Windows 10 on lumia 1020 says no sim

[jeffro02]

My 920 is doing the same thing. I'm not sure how to fix it.

There's a correctly-inserted SIM in there, yes?

[bobsentell]

It is not the sim. I even went to ATT and got a brand new one. The problem is Windows 10 (and I think the lack of Denim). Roll back to 8.1

Ugg, do I need to connect to a PC to rollback?

Me too.... hard reset was the only way out. Thank God I went into it not caring if I lost everything on that phone. Hard reset and not restoring a backup seems to take care of it.

[SDKevin]

Use hardware keys to hard reset.

I just started downloading W10.

Lumia920刚升级之后sim是可以工作的。但重启之后就显示“no sim"。然后再运行Windows insider，选择 fast 项后，显示仍有更新，现在正在更新中。。。
Lumia920 SIM is working after the upgrade. But after reboot it displayed "no SIM". Then run Windows Insider, after you choose fast entry, shows there is still updated, now being updated.

完成后，还是现实 no sim
When finished, still shows no SIM

Same issue here with a 920

Same issue, also cannot open Phone app or settings. Lumia 1020.

Just wait for the next update...
And Can't run Castle Siege!!

Thx, hard reset worked

Same issue here on a 1020. Seems like no cellular is a show stopper for not being able to use Windows 10 mobile. I admit I expected some major bugs, but not lack of cellular access.
