As of 13 August 2026, AI can compare business mobile deals.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open the supplier quote, tariff, contract summary and any recent business mobile bill, then gather the pages or files for every deal you are considering.
   2. Write down the number of connections, typical data use, call and text use, required locations, roaming needs, handset preference, contract length and your buying priorities.
   3. Paste the prompt into a chatbot and attach the source documents, replacing each bracketed slot with your business requirements.
   4. Ask the chatbot to produce the comparison table with a source page or section beside every material figure and term.
   5. Compare the drafted table against each original quote and bill, correcting every charge, allowance, VAT label, contract term and calculation that does not match.
   6. Contact each shortlisted supplier to confirm current coverage, availability, eligibility, price-change rules, early termination charges, roaming and any unclear or missing term.
   7. Send the verified comparison and supplier replies to the person authorised to approve the contract, then record the chosen deal and the evidence supporting it.

   Prompt

   Compare the business mobile deals in the documents and data below for a UK business. Use only facts stated in the supplied material and do not fill gaps from memory or guesswork.
   
   Business requirements:
   - Number of users or connections: [number]
   - Expected monthly data per user: [details]
   - Expected calls and texts: [details]
   - Required locations and travel areas: [locations]
   - Need for roaming: [details]
   - Preferred contract length: [details]
   - Need for handsets or SIM-only: [details]
   - Priorities, in order: [for example lowest total cost, coverage, flexibility, support]
   
   For each deal, extract and compare: monthly charge, one-off charges, VAT treatment, handset cost, data allowance, call and text allowance, roaming terms, network, contract length, minimum term, renewal terms, price-change terms, early termination charges, fair-use limits, setup or activation fees, support terms, and any eligibility or credit conditions. Show the source document and page or section for every material figure or term.
   
   Calculate totals only where the documents provide enough information. Label each total as including or excluding VAT, state the period covered, and show the calculation. Do not estimate missing usage or charges. Mark unknown, ambiguous or conflicting information clearly.
   
   Produce:
   1. A comparison table.
   2. The lowest stated cost for each relevant period, without treating it as the best deal automatically.
   3. The main operational and contractual differences.
   4. A shortlist ranked against my stated priorities, with a reason tied to the evidence.
   5. Questions to send each supplier before signing.
   6. A final section called "Checks I must do myself" covering current coverage at my locations, live availability, eligibility, credit terms, VAT, price changes, cancellation rights and any term you could not verify.
   
   Do not recommend a deal where a missing or ambiguous term could change the ranking. Say exactly what evidence would resolve it.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
