A business mobile contract does not need to be complicated. If you already have handsets, or want the freedom to choose your own devices, a SIM-only plan gives your team the connectivity they need without adding handset finance or unnecessary hardware to the arrangement.
ABC Service now offers business SIM-only contracts on the EE and O2 networks. Every plan includes unlimited UK minutes and texts, with a choice of 10GB, 50GB or Unlimited data. You can select the network and data allowance that best fits each connection, while dealing with a local team based in Tavistock.

WHICH DATA ALLOWANCE IS RIGHT FOR YOUR TEAM?
The right plan depends on how each person uses their phone rather than their job title alone. A team member who mainly uses Wi-Fi and makes calls may need far less data than someone who travels between sites and uses their phone as a hotspot.
10GB may suit users who mainly:
- Make calls and send messages
- Use email and calendars
- Check maps and business apps
- Work mostly on office or home Wi-Fi
- Use mobile data occasionally while travelling
50GB may suit users who regularly:
- Work away from fixed broadband
- Use cloud applications on the move
- Join occasional video calls away from the office
- Access documents and online systems throughout the day
- Use their phone for navigation and hotspot connectivity
Unlimited data may suit users who:
- Rely on mobile data every day
- Work in locations without dependable Wi-Fi
- Use a phone as a hotspot for a laptop or tablet
- Need a more predictable allowance for heavier use
Unlimited does not mean unrestricted in every circumstance. Supplier fair-use, acceptable-use, network-management and roaming policies still apply. Please speak with ABC Service before choosing an Unlimited plan if the connection will be used for persistent hotspotting, high-volume data transfer or unusual business applications.
EE OR O2 - WHICH NETWORK SHOULD YOU CHOOSE?
Both EE and O2 offer business mobile connectivity, but network performance can vary by location, building, travel route and device. The best option for one employee may not be the best option for another.
Before placing an order, we can discuss:
- Where the SIM will normally be used
- Whether the user works in rural areas, offices, warehouses or customer sites
- Indoor coverage requirements
- Regular travel routes
- The expected data usage
- Whether roaming will be needed
Network availability and coverage should be checked for the relevant locations before a contract is started. If you are unsure whether EE or O2 is the better fit, contact us and we will help you compare the practical considerations.
SIM-ONLY MEANS NO HANDSET FINANCE
These contracts provide a SIM card and mobile service only. They do not include a new handset, handset finance or a device replacement arrangement.
That can be useful when:
- Your business already owns compatible handsets
- Employees use approved personal devices under your own policy
- You want to keep mobile service separate from hardware purchasing
- You are replacing a SIM but not the phone
- You want clearer separation between connectivity and equipment costs
Please check that any existing handset is unlocked and compatible with the selected network before ordering. ABC Service can discuss the practical requirements, but handset compatibility remains important when moving an existing device to a new SIM.
ROAMING AND FAIR-USE POLICIES
The plans above describe UK use, and the UK is our primary focus. Roaming availability, roaming charges, international usage, fair-use limits and acceptable-use rules can vary by network and plan. If a user regularly travels outside the UK, works near a border, makes international calls or expects to use large amounts of mobile data, please check the requirements with ABC Service before placing an order. We can confirm the relevant supplier information for the plan you are considering.
