Mobile plan upsells are easy to do badly. Customers have seen enough "special offers" to expect a catch, and the catch is usually in the price or the contract length. A call that is clear about both, and that respects a no, stands out.
This guide offers a script structure for calls where a customer already has a plan with you and you are suggesting a different one. Adapt the wording to your products, and follow your company's rules and local consumer regulations on price statements, contract terms and consent.
Start from the customer, not the tariff
An upsell is easier when it begins with something the customer has said or something visible in their account. Typical triggers:
- Data complaints. "I keep running out of data before the end of the month."
- Travel. "I am going abroad next month and need to use my phone there."
- Family or team changes. "My partner wants to join" or "we are adding a few staff phones."
- A device change. "I am thinking of getting a new phone."
- Bill surprises. "My bill was higher than usual."
- Speed or coverage frustration. "It is slow when I work from home."
If none of these came up, ask one open question before suggesting anything: "How are you finding the plan at the moment?" A customer who says "fine" may not need an offer today, and that is a valid result.
A script structure
1. State why you are calling or raising it. For an inbound call: "Before we finish, may I mention something related to what you just said about data?" For an outbound call to an existing customer: "I am calling about your mobile plan. I would like to check whether it still suits how you use your phone. Do you have two minutes?"
2. Ask two or three questions.
- "How many gigabytes do you usually use?"
- "Do you use the phone mostly on wifi or mobile data?"
- "Do you travel outside the country?"
Write down the answers. Use them in step 4.
3. Check the current position. Look at what the customer pays and any minimum term left. If they are mid-contract, say so before you suggest a change.
4. Offer one plan and compare it plainly. "Based on what you told me, a plan with more data would fit. Your current plan is [price] with [data]. The one I would suggest is [price] with [data]. The difference is [amount] per month. It runs for [term]."
5. Disclose everything that affects cost. State the monthly price, any one-off fees, how long the commitment lasts, when any promotional price ends and what the price becomes afterwards. Say the total over the term if it helps comparison. Leaving something out and mentioning it later damages trust and may breach rules.
6. Ask for a decision and accept either answer. "Would you like to switch, or would you rather keep your current plan?"
Sample exchange
Customer: "My data ran out again before the end of the month."
Agent: "That sounds annoying. May I ask how much you normally use, so I can see whether a different plan would suit you?"
Customer: "Maybe twelve gigabytes, mostly on the train."
Agent: "Thank you. Your plan includes eight gigabytes at [price]. There is a plan with twenty gigabytes at [price], so about [amount] more per month, with a [term] commitment, and the price stays the same for the full term. Would that be useful, or would you rather stay as you are?"
Customer: "I will keep what I have."
Agent: "No problem. If your usage changes, you can ask any time. Is there anything else I can do for you?"
Notice the last step. The agent does not try a second angle.
Handling common responses
"What is the catch?" Answer directly: "The main points are the monthly price, the [term] commitment and the fee if you leave early. I will go through them now." Then do.
"I am happy with my current plan." "Good to hear. If you ever find you are running low on data, let us know."
"It is too expensive." "I understand. Based on your usage, would a smaller plan be better?" Sometimes the right answer is a cheaper plan, and offering it builds credibility.
"I need to ask my partner." "Of course. I can send the details so you can compare, or you can call back whenever it suits you."
"I am still in contract." State the remaining term and any charge for changing early. Do not hide it.
Mistakes to avoid
- Quoting only the monthly saving without the term or fees.
- Pushing a premium plan the customer's usage does not justify.
- Using urgency that is not real, such as an offer that supposedly ends today when it does not.
- Bundling several changes into one yes.
- Asking again after a clear no.
- Talking faster when the customer hesitates.
Practising the call
The skills here are listening for triggers, reading out prices without rushing and staying warm after a no. Each improves with repetition.
Try these drills:
- Trigger spotting. Write six customer sentences and mark which ones are real triggers. Say your follow-up question for each.
- Price statement. Read the price, term and fees aloud until it sounds calm and complete. Time it.
- Decline drill. Practise three ways to accept a no without sounding disappointed.
In DIRI AI, the AI plays the customer on a real voice call, so you can run a scenario where the customer mentions running out of data and you decide how to respond. The report shows moments worth retrying. See the sample dialogues for an example and how scoring works for what is covered.

FAQ
Should I upsell on a complaint call?
Resolve the complaint first. Only raise a plan afterwards if it links to something the customer said.
How many options should I present?
One, based on what they told you. If they ask for alternatives, add a second.
Do I need to read out the contract terms?
Follow your company's rules and local regulations. As a good habit, state the price, term, fees and any price change in plain words.
What if a customer says yes but sounds unsure?
Check: "Would you like a moment to think, or are you happy to go ahead?" A confirmed yes is better than a quick one.
