How it works

A simple, structured process designed for UK businesses managing multiple mobile lines.
It’s built to help procurement and operations teams get accurate quotes without unnecessary back-and-forth or sales pressure.

Step 1
Tell us the basics
Company and contact details, number of mobile lines, and whether you’re looking at SIM-only, handsets, or a mix.
This step ensures we understand your setup from the outset — particularly important for businesses managing 5 or more users.
Step 2
Your current setup
Contract timelines, network preferences, and any device requirements.
Capturing this upfront helps decision-makers avoid rework later and allows us to compare tariffs that genuinely fit how your team operates.
Step 3
We do the chasing
As an independent UK business mobile quote service, we compare suitable options across the major networks and return best-fit pricing — without locking you into a single provider or bombarding you with follow-up calls.

Frequently asked questions

Clear answers to common questions about our business mobile quote service.

Why do we focus on 5+ mobile lines?

Business mobile pricing works very differently once you have multiple users. Networks unlock better tariffs, stronger negotiation and more flexible options when accounts reach 5 or more lines.

Most comparison sites are designed for 1–4 phones, which often leads to generic quotes, missed discounts and unnecessary follow-up calls. We focus exclusively on teams so we can get the details right first time.

If you’re managing multiple mobiles — whether SIM-only, handsets or a mix — our process is built to save time, reduce hassle and deliver accurate, business-grade pricing.

How many lines do I need to use B2B Mobiles?

B2B Mobiles specialises in UK businesses requiring 5 or more mobile lines. Our quote process is designed around multi-line business requirements rather than consumer or single-user deals.

Can you compare business SIM-only deals?

Yes. We compare business SIM-only options for companies that want to keep their existing phones, as well as handset-inclusive contracts where new devices are required.

Which mobile networks can you compare?

We compare suitable business mobile options across the major UK networks, including EE, Vodafone, O2 and Three, based on your requirements and network preferences.

Can I keep my existing mobile numbers?

In most cases, yes. Existing business mobile numbers can normally be retained when moving to a new contract or network, subject to the normal porting process and your current account status.

When should I start comparing deals before my contract ends?

You can start planning at any time, but the most relevant options are usually available closer to your renewal date. Tell us how long is left and we’ll use that to guide the quote process.

Will I receive sales calls from multiple providers?

No. We collect the key information upfront so we can compare suitable options without passing you into an endless cycle of sales calls. We’ll use the contact method you select in the quote form.
