Tips for Contacting T-Mobile

• When calling the T Mobile customer service number, please be respectful and courteous toward the employees. Their staff are well trained advisors that will not stand for verbal abuse.

• Before you contact T Mobile UK customer service, have your details ready. This is usually your mobile number, your account number (the one you use online) and some personal details to confirm your data protection authorisation.

• You will hear the voice prompting service for “EE” when you ring the T Mobile contact number. This is because it has been phased out. Please be accurate in your answers and your query will be dealt with as fast as possible.

Frequently Asked Questions

My phone isn’t receiving texts and I can’t make calls, what do I do?

You signal could be down. Please check to see if there is down-time in your area. This usually means that the signal will be lost due to some work being done. You can check this by going to the EE website and checking the coverage in your area by inputting your postcode.
If this is not the issue, you should restart your device, then reset your network settings if necessary. Or you can check to see if you’ve paid your last bill.
If you need help with these options, please call the T-Mobile telephone number provided here and speak to an agent.

Why does my bill increase every year if I’m using the same tariff?

The increase in your bill is related to the RPI (Retail Price Index). This is the measure that is calculated by looking at consumer pricing and inflation. This is usually no more than about 1 – 2 % and won’t affect your bill in a significant way. If you need a cheaper monthly premium, please call the T-Mobile contact number on this page and talk to an advisor about changing your tariff.

About T-Mobile

T-Mobile was a mobile network operator based in the United Kingdom and owned by Deutsche Telekom since 1999. Deutsche Telekom struck a deal with Orange UK in 2009 to merger the T-Mobile and Orange brands and rename the new company – EE, making it the UK’s largest mobile network.

The mobile network Mercury One2One was created and launched in 1993 as an introduction to the mobile network market. It was a pioneer in the way that it was the first GSM 1800 network in the world.
They offered both pay-monthly and Pay As You Go options.

In 2009, Deutsche Telekom (who owned T-Mobile) and France Télécom (who owned Orange), made an announcement that they were to merge their businesses in the United Kingdom. EE was started (reference) and slowly and by 2015, it was completely phased out until as of February of 2015, no new or existing customer can use the T-Mobile brand.

The mobile network operator was not without controversy. In 2009 they were under investigation by Mohit Information Commissioner’s Office for the suspected illegal trade of personal data by some of it’s employees. This was a serious offense that potentially affected millions of customers.

This was admitted by the company, that said that it was a lone employee taking advantage of a security system that should have been more secure.
