Hopefully this might help someone...
In order to get your gigabag up and running on a TP-Link M5350, you must change the settings. You won't have any connectivity until you do. Looking around on the interweb some people seem to have instructions in Chinese, or no instructions at all.
I got a giffgaff SIM for dedicated use on a TPlink 5350.
I have got similar settings to you and I can get on internet with all the devices I want.
However, the unit persists in telling me that I am connected to O2 network!!! I have network profile called O2 but it has the giff settings as well. I am confused about which network internet I am logging on too. Any Ideas
I have just bought one M5350 TP-LINK and follow your instructions but it does not work at all.
I have activated a 3 gigabag data, I see that I am connected to the network, some data are received and sent, but it does not work for me.
I have written also to the support desk, but nobody fix the problem.
I realy apprecitate if somebody can share his experience. The Router M5350 TP-LINK is very esasy to setup but I am wondering if it works with GiffGaffgigabag data.
Thank you so much for this. After reading all of the positive reviews on Amazon about this MiFi I took the plunge and bought one. Works great with GiffGaff. The MiFi is amazing value for money and (as its unlocked) I also use it when abroad in Germany with a Tchibo data SIM (02 Network also!) This costs 20 Euros (about £19) for 5gb (one calendar month).
