Sky and EE have generated the joint fewest official complaints among pay-monthly mobile customers, new quarterly figures from the telecoms watchdog have revealed.

Conversely, BT Mobile was found to have racked up the highest number of complaints for the fifth time in a row.

According to Ofcom, the most common gripes among BT's pay-monthly customers related to poor complaints handling (38%), issues when switching to another provider (31%) and billing problems (14%).

If you're fed up with your provider, or simply need a new phone, why not compare pay-monthly deals with Carphone Warehouse? (note: we may receive a small commission for any purchase you make)

Total complaints figures far higher

The graphic from Ofcom below highlights how all the major networks compare and covers the three months between April and June 2023, which are the latest figures available.

It's worth pointing out that, while the number of complaints appears low for all mobile providers, these are issues that customers have needed to escalate to Ofcom as they've been unable to resolve their issues directly with their provider. 

The actual number of complaints made directly to network providers is far higher: Ofcom's data suggests that more than one in eight (12%) mobile customers said they had a reason to complain over the course of last year.

Tesco Mobile Vodafone both generated a total of three complaints per 100,000 customers, which is also the industry average.

At the other end of the table, BT Mobile was responsible for eight complaints per 100,000. 

This is the highest among all the major firms and the fifth consecutive quarter that it has been responsible for the most complaints.

Virgin Mobile and O2 were second from bottom with five per 100,000 customers. 

Which providers offer consistently good service?

Ofcom publishes data on the number of complaints it receives about each of the big telecoms providers every three months.

Looking at such a short period can be unreliable – any provider can have a temporary problem that dramatically skews the figures.

In order to give you a clearer picture of how the mobile network giants consistently fare, we've listed the complaints figures for the last six quarters (18 months) in the table below.

If you're fed up with your provider, take a look at our pain-free guide to cancelling your contract then search for a new mobile phone deal on Carphone Warehouse or another comparison site.

Mobile coverage

Practically speaking, the most important thing to keep in mind when signing up for any phone contract is the coverage and reception offered by the operator (you can read about the best networks for signal and speed here).

Ultimately, an extremely helpful call centre is of little use if you can't even phone them in the first place!

To make sure you don't live in a particular network's 'blackspot', the links below will take you to each network’s coverage map or coverage checker, so you can get a decent idea of the coverage you can expect where you live.
