The portable firewall of China

I am currently away on training in London so made the drastic decision to travel light and only bring my Ipad and a mifi. Okay I did bring some more gadgets but settled that I only should require the Ipad. My thoughts will be blogged after the week is up.

The mifi itself has been a god send as I put it in my back pack attached to a battery extender which gives me wifi for 8 hours. More than enough to get me through the day with my devices.

I no longer subscribe to a contract for the mifi but have opted to purchase data sim cards from EBay or other outlets dependent on what best deal I can get. Recently I have been purchasing Vodafone sims from eBay at £8 for 3gb as the signal strength has been very good and the speeds acceptable.

There has been a few reports in the Press that vodafone has been blocking Voip and I reported recently that Cydia had been blocked on my Ipad

However I am finding that more sites are being blocked by vodafone content control for example Iplayer streaming, twitgo and yfrog and even Skype. Now all it takes is a phone call to customer services to remove the lock but because I am purchasing new sim cards this is too much of a pain as it requires registration each time. Now you could say why don't get a contract but the prices are poor for 3gb and I am saving through what I am doing.

To get around these restrictions so I can post to twitter with pictures or use Iplayer (I have paid for the bandwidth!) I am using a VPN. Through jail breaking my iPhone and ipad I am running a tool called Guizmovpn and for 4.99 € I can run an openvpn connection over SSL to an openvpn provider. Because this encrypts and tunnels my traffic I am able to do my tweeting with photos using a service called freedomvpn for 8€ per month. Unfortunately whilst cheap it does not allow me to connect all devices at once on the cheapest tariff. Therefore I am now trailing a VPN pro package with Hidemyass.com for £7.66 per month. This allows up to 3 devices to be connected and they offer openvpn, pptp and l2tp VPNs. I have yet to still try their openvpn offering but pptp works fine. I am looking at setting up a VPN at home and using my home broadband to save in the monthly subscription. The only technical issue I have is the iPhone disconnects automatically and doesn't reconnect when its not in use. Whereas Guizmovpn stays connected all the time and reconnects as and when required.

The VPN services are also useful in free wifi areas to hide my credentials from fire sheep wanna be kiddie script hackers so I can ensure I am secure.

What has surprised me is how much Vodafone is restricting especially sites such as yfrog, twit go and Cydia. None of these sites causes problems albeit they may argue Cydia means jail broken devices. Whilst I understand they want to protect their networks and consumers from bad things they seriously need to need to re-evaluate their filters. Ultimately I have paid for a connection to the internet and expect a level of service that allows me to use it. However I feel each time I pass wind there is someone over my shoulder saying you cannot do that.

I accept there are terms for using their network but this recent example feels like big brother gone mad or it's a preemptive trial for charging more for certain types of traffic.

Thankfully my technical skills helped me out here but what about your normal user in the street?

I believe as Vodafone and the other networks follow suit with this Orwellian approach to traffic management that VPN and other proxy based solutions will become more prevalent.

Is there a real voip solution for mobiles so I can have a data only tariff?

My mobile contract is due to finish in November and I am contemplating where to go next. I currently pay £65 per month that gives me 10gb of data, 500 text , free national phone calls and 600 minutes of talk time for other numbers.

Since getting broadband again my data usage has dropped to under 3gb, I only send under 100 texts a month and I hardly make or receive any phone calls. Therefore I am thinking should it be payg, sim only or mobile broadband. I know I don't want a contract and to pay for unused call time.

I was thinking that I want a data only tariff and use a voip service such as Skype or Truphone for making calls and send text. However I am not convinced that voip over a 3g network is mature enough to be a viable option. If google voice had been available then I could just keep the data tariff and have one number for incoming but assign several numbers to it for example the mobile broadband. Whereas I have used Skype and it only runs really on the n900 whereas I am currently using an iphone and have found it to be a kludge.

My objective in all this is to save money but have a cheap reliable service to make and receive calls when needed but also be able to send/receive the few texts but have a 3gb data Bolt on. Ideally the calls to landline numbers should be free after paying a subscription such as my £3.30 per month to Skype. But the problem with the latter is I cannot text. With trephine I can text but their call tariffs are not as cheap as Skype

I will continue to do research over the next few months before I decide but ultimately a talk time and text tariff are a waste on me as only data is needed. But again the data only tariffs are very poor and I don't believe I could transfer my existing mobile to a mobile broadband only sim.

So I am between a rock and a hard place but hopefully I will find an answer soon.
