Office number on your mobile
Your office number, on the phone in your pocket. No app, no second handset.
A TISA Pocket Office SIM turns your mobile into an extension of the business phone system. Office calls ring on it, and calls you make show the office number.

How it works
One mobile. The office number, in both directions.
When a customer rings the officeIt rings you.
- Your mobile rings alongside the desk phones, in the same ring groups.
- Your greeting answers first, with the same menu as the office.
- Missed it? Voicemail goes to your email.
When you call a customerThey see the office.
- The office number shows, not a personal mobile number.
- From the phone’s own dialler, with no app to open.
- Calls can be recorded, the same as on the desk phones.

Only the people who answer the office line.
A Business SIM is a work mobile on its own number. Pocket Office adds the office number to that same SIM. Mix the two on one account.
Questions
What people ask before they put the office on their mobile.
Can I have my office number on my mobile?
Yes. A TISA Pocket Office SIM makes your mobile a full extension of your business phone system. The office number rings on the mobile, and when you call out, the person you call sees the office number.
Do I need an app?
No app is required. It works in the phone’s own dialler on a compatible mobile. The mobile and desktop apps are included too, if you want them.
What is the difference from a normal business SIM?
A Business SIM is business mobile service on a work mobile number. Pocket Office adds a Cloud PBX extension to that same SIM, so it also carries the office number.
Do we need a Cloud PBX as well?
No. A Pocket Office SIM can run on its own. If you have Cloud PBX, the mobiles appear in the same portal as the desk phones and join the same ring groups and call flows.
What does it cost?
From £8.50 a SIM a month ex VAT on a 24 month term, or £10.10 on 12 months. That entry plan has no mobile data. Plans with data are in the table above.
