Pros & cons

SIM only pros and cons

SIM-only prices can be a lot cheaper, but you don't get to upgrade your phones. If you are on a tight budget, SIM-only and E-SIM options could be a great deal for you, but slow, out of date hardware and shorter battery life could cost you more.

Lower monthly costs - SIM-only contracts are significantly cheaper than handset deals since you're not paying off the cost of a device, making them ideal for businesses looking to reduce their mobile overheads.

Flexibility and shorter contract terms - Most SIM-only deals are available on 30-day rolling or 12-month agreements, giving businesses the agility to scale up, switch providers, or renegotiate as their needs change.

Keep your existing devices - Businesses that have already invested in company handsets can continue using them without being tied to unnecessary hardware upgrades, maximising the return on existing assets.

No subsidised device included - Businesses that need new or upgraded hardware will have to purchase handsets separately, which can mean a higher upfront capital cost.

Shorter terms can mean less price stability - While flexibility is a benefit, rolling contracts can be subject to price increases at renewal, making long-term budgeting less predictable compared to fixed handset deals.

Fewer incentives and perks - SIM-only deals often miss out on the added value that comes with full handset contracts, such as device insurance, trade-in schemes, or bundled accessories.

I had an outstanding experience working with Callum at Connection Technologies. He was incredibly helpful in identifying the best deal together with the best signal coverage for my business, and managed the entire migration from our previous provider without a single hassle. Callum provides fast, professional service and is always available when you need assistance. It’s rare to find this level of support, I’ve never experienced anything like it! Highly recommended.

5-star service from Callum! He rescued us from O2’s dwindling/infuriating customer service and secured a fantastic Vodafone deal that’s saving us 40% per handset. I have a happy team with their shiny new iPhones. Having a dedicated person like Callum to talk to instead of a faceless call center makes all the difference. Connection Technologies is definitely the way to go - Callum couldn't have been more helpful during the "sell" and I am confident that will continue over the 3-year contract.
