There are no transparent proxies or devices that will block any sort of traffic.
NAT can be a problem with some protocols, but as mentioned all our data SIMs have static IPv4 addresses and there is no NAT invoved.
You pay monthly for the SIM, so you can cancel it after the first month if you wish, or carry on using for as long as you need to.

Real fixed IPv4
Normally a Data SIM is allocated a single fixed legacy IP address. This is used when you connect and you do not need to set any username, password or APN to use the Data SIM in the UK. Simply insert in to your equipment.
The service has no filtering. The combination of fixed real legacy IP address and unfiltered connection gives you a real connection to the Internet. No longer will you have trouble accessing a site that your mobile provider has mistakenly decided has adult content. No longer will you have problems sending an email via your corporate mail server because port 25 is blocked. This is a real Internet connection on your mobile device. You can even control the reverse DNS for your IP on our control pages. There is no NAT involved, you can ping your iPad!
How about IPv6?
IPv6 is not yet available directly, but can be routed via IPv4 (protocol 41) tunnels if required. We hope to have native IPv6 soon and so provide a full Internet access service on mobile data.
Corporate network or wholesale customers
Our voice and data SIM cards are ideal for a corporate network or for a wholesale customer to set up their own mobile service.
We can offer branding with professional quality SIM printing and pre-set settings.
Broadband backup
You can specify a username and password for a DSL line and receive routing for the IP addresses for that line - this allows the Data SIM to be used in a mobile router to provide a backup for DSL lines with full legacy IP routing including blocks of IPs, and full 1500 byte MTU support.
Technical details
Data SIMs are provided on a full size SIM card with push out mini-SIM, and within that a push out micro-SIM. We also print the nano-SIM outline. Cutting the Data SIM down is easy but at your own risk (to SIM and mobile device), so we suggest doing so before you activate the Data SIM. Nano SIM cutters are available in the Internet but otherwise small straight bladed nail scissors work well.
The APN need not be set in the UK, if required then set to m2m.aql.net. Username and password are not normally needed unless using as ADSL backup or with corporate L2TP relay (see below).
The legacy IP is allocated automatically. The remote legacy IP (i.e. our end of PPP link) is usually not meaningful and may show as 10.64.64.64. We can route blocks of legacy IPs as well. Full 1500 byte MTU is supported.
The Data SIM only works on the Three UK network, you can check for coverage with the tool below.
Roaming
Roaming is disabled at present.
Calls and Texts
The Data SIMs do not provide voice calls or texts. We offer a SIP2SIM voice SIM service if you need these.
Custom Printed Cards
We can print our own artwork on SIMs, see our SIM Branding page.
