Mobile Deals Built for Startups
When you are launching a startup, you need a mobile plan that is cheap, flexible, and scales with you. Long contracts and expensive handset deals are not what early-stage businesses need. That is why we recommend starting with SIM only deals on 30-day rolling contracts — maximum flexibility, minimum cost, no commitment.
Compare The Networks helps startups compare deals from EE, Three, Vodafone, and O2. All prices exclude VAT, and all tariffs include annual CPI + 3.9% price increases.
Startup Mobile Plan Comparison
| Plan | Monthly Cost | Data | Contract | Credit Check |
|---|---|---|---|---|
| SIM Only Basic | From £6/mo | 1GB | 30-day rolling | No Easiest |
| SIM Only Unlimited | From £10/mo | Unlimited | 30-day rolling | No Best Value |
| 12-Month SIM Only | From £8/mo | 10GB | 12 months | Yes |
| Handset Contract | From £15/mo | Varies | 24 months | Yes |
For most startups, we recommend starting with a 30-day SIM only deal. No credit check, no long-term commitment, and from just £6/month. You can always upgrade later as your business grows.

Get Startup QuoteWhy Startups Should Choose SIM Only
- No credit check — SIM only packages require no credit check. Perfect for new companies with no credit history
- 30-day flexibility — cancel or change anytime. If your startup pivots, your phone plan can pivot too
- From £6/month — the cheapest business mobile deals are SIM only. Spend your funding on growth, not phone contracts
- Use your own phone — most founders already have a good phone. Add a business SIM and keep personal and work separate
- Scale instantly — add new SIM cards as you hire. No paperwork, no waiting
Virtual Landline: Look Professional from Day One
A virtual landline gives your startup a local business number (020, 0161, 0113, etc.) from just £6/month. Calls forward to your mobile, so you can answer professionally from anywhere. This is different from VoIP — a virtual landline is simply a number that forwards to your mobile, while VoIP is a full phone system.
- Professional image — a geographic number makes your startup appear established
- No office needed — work from home, a co-working space, or a coffee shop
- Separate work calls — keep your personal mobile number private
- From £6/month — cheaper than a PO box or virtual office address
When to Upgrade from SIM Only
As your startup grows, there are good reasons to move beyond basic SIM only:
- 5-10 employees — consider multi-line deals for volume discounts and single-invoice management
- Client-facing roles — iPhone or Samsung handset contracts give staff professional devices
- 10+ employees — add a VoIP phone system for call management, auto-attendant, and team extensions
- Remote/hybrid teams — remote worker deals with unlimited data and MDM for security
Tax Benefits for Startups
Business mobile costs are fully tax-deductible. If your startup is VAT-registered, you can reclaim VAT on all mobile expenses. Even SIM only deals on 30-day contracts qualify as a business expense. Read our full guide: How to Claim Your Business Mobile as a Tax Expense.
