T-Mobile has always been among the fastest of the mobile broadband providers. Although it’s trumped by Vodafone in terms of nationwide median speed, it recorded a faster top speed in our central London tests, suggesting that it may be worth considering if you live in the major cities.

Reviews
The T-Mobile service compresses images by default, making the BBC News homepage look like a smeary mess. Even more annoyingly, the compression can’t be switched off using the software that comes with the stick; instead, you have to download the separate Web’n’Walk Accelerator software, which switched off the compression despite error messages to the contrary.
T-Mobile’s refusal to penalise customers financially for breaking its data cap should be applauded, although the company does reserve the right to throttle or disconnect those who abuse such generosity.
T-Mobile is a good option if you want to use a mobile broadband dongle as backup for your home ADSL/cable service: a day’s access can be bought for only £2, with modems starting from £20. Pay monthly plans start from a reasonable £15 per month (£10 for the first three months).
