Can you use a Mifi to set up a mobile network without needing a sim card?

To clarify what I am asking, I am travelling next month and I will need to be able to set up a wifi network when I am out and about so my devices can communicate, so I had thought the best option would be to get a Mifi as they run off battery, however as I dont need to get on the internet I dont want to have to bother to get a sim card to make it work.

Will this plan work? Can I just fire up the Mifi without a sim and then connect my devices to it?

Not sure, can test in a bit when not using the mifi so heavily.

won't work, i've tried something similar before.

But maybe the newer mi-fi allows it???

Which one did you test with? I've the 21mbps one. e586 I think

NOPE. Doesn't work. They are cheap hotspots... not proper routers.
What are the devices, and what (why? :p ) do they need to communicate with another?

maybe get a payg sim (or an old one you have laying around) and don't top it up?

but depending what devices you have just set one up in infrastructure mode

Ah boo, annoying it doesn't work!

The devices are an iPad and an iPod, there is an app I use when rowing that communicates between the two apps but needs a network to do it obviously, here in the UK I just use personal hotspot, but overseas I don't want to get done for lots of data so I would turn off 3G but that also turns off personal hotspot. Thought mifi would be a way around this but sounds like not, grrr

Hi. On my iPad, hotspot works with a sim in even if the sim has no signal.
So it can be used as a virtual router even with no signal.
Not sure if this would work with your mifi as I haven't got one, but if you bung a free samba sim in it or something so you cannot get charged anything and it may still give a wifi network. Maybe try it with a payg sim with no credit on it if you have one.

Thanks for the feedback, Like you say the way forward might be tongetba mifi with a blank sim just so it works and I don't get charged

One other thing I'd thought was, as mentioned, the personaly hotspot goes if you turn off data, but I wonder if personal hotspot staysmifmyouve disabled roaming and are overseas? If it did then I would be able to use personal hotspot to do what I want but wouldn't get charged as no roaming

When you disable roaming data connection never comes up - don't think it will work.
Ideally you want a phone with WiFi hot spot and SIM card that has roaming blocked on provider level. It will connect to data network, but won't be able to get any data.

I think you should get something like that: http://www.tp-link.com/en/products/details/?model=TL-WR702N

There is also product from Asus: http://www.asus.com/News/4eBKfIF7GE2NGIxP

Also, more expensive version: http://www.tp-link.com/en/products/details/?model=TL-MR3040

Thanks for that, in my situation I would need to have a battery powered router (wouldnt have a plug or laptop to hand) so the second TP one looks interesting, that being said im not sure if it will work to produce a network if it doesnt have a USB 3G stick included

I think ive found a market/use that no-one has thought of before :p Network without 3G

I would call it network without computer. There are plenty of laptop WiFi cards that can act as a hotspot.
