SIM: quick to start
Reps already have the phones and SIMs, so there is no line to provision.

What Is The Difference Between SIM And Cloud Calling?
SIM calling uses the mobile network and the SIM inside a phone. Cloud calling, also called cloud telephony or VoIP, runs over the internet on a virtual number. The main practical difference is who controls the number: with SIM calling it usually sits with the rep, and with cloud calling it sits with the company.
Neither is better for every team. A field team calling from mobiles may lose time moving to a cloud line, while a team selling across borders may outgrow SIM calling quickly. Many teams end up using both, which is why tracking them in one place matters.
Where Each One Is Stronger
Each option has real advantages, so match them to how your team sells.
SIM: works on mobile network
Calls do not depend on a good internet connection, which helps out in the field.
SIM: familiar number
Customers see a normal mobile number, and existing contacts may already know it.
Cloud: company-owned number
The number stays with the business when a rep leaves.
Cloud: shared line
One business number can serve a team, and a virtual number is not tied to one phone.
Cloud: local presence
Virtual numbers can give you a local number in a market where you have no office.
How To Choose In Four Questions
Work through these with your sales lead. The answers usually point to one option.
SIM vs Cloud Calling Compared
The factors that usually decide it. Costs vary a lot by country and provider, so get real quotes.
| Factor | SIM calling | Cloud calling |
|---|---|---|
| Connection | Mobile network | Internet |
| Setup | Use existing phones and SIMs | Buy a number and set up an account |
| Cost model | Your mobile carrier plan | Usually per number, per user or per minute |
| Number shown | Rep's mobile number | Business or local virtual number |
| Number ownership | Usually tied to the SIM holder | Stays with the company |
| Call quality depends on | Mobile signal | Internet connection |
| Selling abroad | International carrier rates may apply | Local numbers may be available |
| Compliance | Calling and recording laws apply | Calling and recording laws apply |
| In Eazybe | Tracked on Android | Tracked, with voice numbers in the US, Canada and Puerto Rico |
Choose SIM calling if
your reps already sell from Android phones, work in the field and mostly call customers in their own country.
Choose cloud calling if
you need a company-owned number, a shared business line or a presence in another market.
Use both if
you have field reps and an inside team. Track both in one place so the customer record stays complete.
Typical Choices By Team
These are starting points. Your own market and carrier rates can change the answer.
Field sales
Usually SIM calling, because reps are on the move and already have phones with them.
Cross-border inside sales
Usually cloud calling, because local numbers and a shared line matter more.
Mixed teams
Often both, with one record per customer so managers are not checking two systems.
Whichever You Choose, Keep One Record
The choice of phone line matters less than whether you can see what happened afterwards. Eazybe logs SIM and virtual calls beside WhatsApp chats, so you can change your mix later and still keep the customer history.

FAQ
Frequently Asked Questions
Quick answers for teams deciding between SIM calling and cloud telephony. Eazybe sells both options, so weigh this with your own quotes.
Is SIM calling cheaper than cloud telephony?
It depends on your carrier plan, call volume and country. If reps already have unlimited local calling, SIM calling can cost little extra. Compare it with a real cloud quote that includes numbers, users and minutes.
Do customers answer SIM calls more often?
SIM vendors often say so, but we have not seen independent data that proves it across markets. Test it on your own lists by comparing answer rates over a few weeks.
What is cloud telephony?
Cloud telephony runs business calls over the internet instead of a physical phone line or a SIM. The numbers and call data are managed through an online account.
Can I use SIM and cloud calling together?
Yes. Eazybe tracks SIM calls on Android and virtual calls, and saves both beside the customer's WhatsApp chats.
Who keeps the number if a rep quits?
With a SIM, it depends on who owns the SIM. With an Eazybe voice number, the number and customer history stay with the company.
Which has better call quality?
It depends on the connection. SIM calls rely on mobile signal, and cloud calls rely on your internet. A rep with a weak office connection may do better on SIM, while a rep in a low signal area may do better on cloud.
Which is better for selling abroad?
Usually cloud calling, because a virtual number can give you a local presence in that market, while a SIM may charge international rates. Our voice numbers cover the US, Canada and Puerto Rico.
Do calling and recording laws differ between them?
No. The rules follow the country you call and how you contact people, not the type of line. Rules change, so take advice for your own market.
Can I start on SIM and add cloud calling later?
Yes. Eazybe tracks both, and a voice number is an optional add-on on every plan, so you can add one when your team needs a shared line.
Which is better for field sales?
Usually SIM calling, since it works over the mobile network and reps already carry the phone. Cloud calling needs a reliable internet connection.
