3G SMTP Email Server Settings

3G SMTP Servers for Three, Vodafone, O2, Orange, T-Mobile in the UK

Normally, unless you have a corporate email account you have to change your outbound (SMTP) server depending on how you are connected to the Internet.  This is not only a waste of time, but frequently either mobile providers servers are unreliable or their required settings change without any prior notification.

Listed below are some of the commonly used 3G SMTP Servers for users in the UK.  As you can see, most providers have multiple servers and it is not always possible to establish the correct server to use without much trial and error.

How to keep the same SMTP Settings wherever you are...

For most users, the most important consideration is to be able to send and receive email quickly and easily, using whatever Internet connection is available.  Frequently changing the SMTP server settings is a real pain and gets in the way when you just need to send an email. 

Fortunately there is an alternative and cheap solution to the problem, and this is the method we use here at Mobile-3g, it's called SMTP2Go and for as little as $1.99 a month, SMTP2GO provide a SMTP server that you can use from ANYWHERE - Home, work, friends wireless connection, wireless hotspot or 3G dongle.  There's a free 7 day trial so you can check out how easy it is to use as well.

Even though we work in IT and have no problem changing server settings as and when we need to, SMTP2GO saves us time and effort and lets us email from anywhere with an Internet connection.  We highly recommend their service and encourage you to try it for yourself:
