Introduction

For UK-based small and medium businesses (SMEs), staying connected is more than just convenience—it’s essential for efficiency, growth, and competitiveness. Whether you’re dealing with EU suppliers, collaborating with partners abroad, or have staff travelling inside the UK and Europe, you need a mobile plan that delivers value without surprises. Gleesim’s Business SIM Only – O2 50GB Plan does exactly that. At just £18.00/month (excl. VAT) on a 24-months contract, this plan gives you unlimited UK calls and texts, free UK to EU calls, free roaming in the EU, and substantial data to power your business in the UK – all over O2’s reliable network.

What is the O2 50GB Business SIM Only Plan?

Here are the plan’s core features from Gleesim:

Key Benefits for SMBs

Here are the compelling advantages for small and medium businesses:

1. Significant Data Allowance with 5G Speeds
   With 50 GB of high-speed 5G data, businesses can support team communications, video conferencing, cloud collaboration tools, remote access, large file transfers and more without constant worries about going over data limits.

2. Unlimited UK Calls & Texts
   Freedom to call and message across UK without boundary: whether it’s internal team communication, handling customer calls, or managing business operations, having unlimited UK calling and texting removes constraints and surprise costs.

3. Free UK-to-EU Calls
   If your business has clients, partners or suppliers in Europe, the inclusion of up to 500 minutes/month of free UK → EU calls gives you strong cost savings. It’s especially useful for regular cross-border voice communications where VoIP isn’t sufficient or suitable.

4. Free EU Roaming
   Traveling staff or businesses with operations in both the UK and EU benefit greatly. Free roaming (with fair usage) means you can use your broadband, make calls, send texts, access online tools just like at home—without roaming surcharges.

5. Predictable Business Costs
   A fixed monthly cost of £18 (excluding VAT) for a full two years, plus a known annual RPI tweak, helps with budgeting. There are no unexpected roaming charges or surprise call/text fees — transparency that businesses demand.

6. Best Coverage in the UK via O2
   O2 is known for broad coverage and reliability. Choosing O2 ensures that you are backed by one of the leading UK networks, which can matter for rural locations, travel between sites, or remote working where signal strength is critical.

7. Long Contract Helps Lock-in Value
   The 24-month contract helps lock in this favorable deal. Over time, increases in telecom costs, roaming tariffs, or network upgrades can inflate bills elsewhere; this plan helps you avoid those inflation surprises for two years (aside from the stated RPI uplift).

Who Should Choose This Plan

• Businesses that regularly call Europe (suppliers, partners, clients) from the UK

• SMEs with staff who travel frequently to EU countries and need to stay online/data enabled

• Remote/hybrid teams based in both UK & EU or working across borders frequently

• Businesses looking for fixed, transparent telecom costs without hidden fees

• Companies needing strong data capacity in the UK plus reliable network coverage

Comparison with Other Plans & Market Trends

In the current UK telecom market:

• Many “business sim only” deals either limit roaming or make “free EU data / calls” less generous. Gleesim’s free EU calling + roaming with fair usage gives an edge.

• 5G usage is rapidly increasing in business applications: video calls, remote work, mobile cloud services. Data allowances of 50GB+ are becoming expected, not luxury.

• Contracts of 24 months are standard in business-grade plans, allowing providers to guarantee service levels, and businesses to lock in lower rates.

• Customers now demand best coverage; network reputation matters, especially for field teams or multi-location businesses.

Potential Considerations & Limitations

To be fully transparent, it’s important to note some constraints:

• Fair Usage Caps: EU roaming is free but with a monthly cap (35 GB). Likewise, free UK-EU calls are limited to 500 minutes/month. Very heavy users might exceed these and incur extra costs.

• Contract Duration: 24 months means commitment; early exit may require penalties.

• Annual Price Increase: The RPI uplift every April (£1.50) must be anticipated in financial planning.

• Excluding VAT: Price excludes VAT; businesses must account for this in finance.
