How to Keep Your Home Number While Traveling Abroad

One of the biggest worries travelers have is missing important calls while abroad. Your bank, your doctor's office, your child's school, your clients — they all call your home number. If that number goes to voicemail for two weeks, you might miss something critical.

This guide explains how to keep your home phone number fully operational while traveling internationally with an eSIM.

The Problem: Your Home Number Abroad

When you travel internationally, you have two uncomfortable options with a traditional setup:

Option 1: Keep roaming active. Your home number works, but every incoming call costs $1-3 per minute in roaming charges. Outgoing calls are even more expensive. A 10-minute call from your bank could cost $30.

Option 2: Turn off roaming to save money. Your home number effectively goes dark. Calls go to voicemail. Important people cannot reach you.

Neither option is good. You either pay outrageous fees or become unreachable.

The Solution: TripoSIM HomeLink

HomeLink is a call forwarding service that routes your home number's incoming calls to your TripoSIM eSIM connection. When someone calls your regular number, the call reaches you over data — no roaming charges, no missed calls.

Here is how it works:

1. You set up conditional call forwarding on your home carrier before you leave. This tells your carrier: "If I do not answer, forward the call to this number."
2. The forwarding destination is a HomeLink DID number — a virtual number assigned to your TripoSIM account.
3. When someone calls your home number, your home carrier forwards it to the HomeLink DID.
4. HomeLink routes the call to your phone over your eSIM data connection using VoIP technology.
5. Your phone rings through the TripoSIM app, showing the original caller's number.
6. You answer and talk using your eSIM data. The call quality is comparable to WhatsApp or FaceTime calls.

The caller has no idea you are abroad. They dialed your regular number and you picked up. That is the entire point.

Setting Up HomeLink: Step by Step

Before your trip:

1. Log in to your TripoSIM account and go to [HomeLink settings](/homelink).
2. Activate HomeLink for your account. You will be assigned a DID (virtual phone number).
3. Note the forwarding number provided.
4. Set up call forwarding on your home carrier:

• iPhone: Settings > Phone > Call Forwarding > Enter the HomeLink number
• Android: Phone app > Settings > Call forwarding > Forward when unreachable > Enter the HomeLink number
• Or dial from your phone: Most carriers support codes like `*62*[HomeLink number]#` to set up forwarding for unreachable calls.

1. Test it by calling your home number from another phone while your home SIM is disabled.

During your trip:

1. Make sure your TripoSIM eSIM is active and has data.
2. Keep the TripoSIM app running in the background.
3. When a call comes in, your phone rings through the app with the caller's number displayed.
4. Answer normally. The call uses your eSIM data connection.

After your trip:

1. Disable call forwarding on your home carrier (Settings > Phone > Call Forwarding > Off, or dial `##62#`).
2. Your home number returns to normal operation.

Supported Countries

HomeLink works in 18+ countries where TripoSIM has DID number availability:

United States, United Kingdom, Canada, Germany, France, Netherlands, Australia, Spain, Italy, Ireland, Austria, Belgium, Sweden, Switzerland, Portugal, Japan, South Korea, and more being added regularly.

If your home country is on this list, you can receive forwarded calls while traveling anywhere in the world — as long as your eSIM has an active data connection.

How Much Data Do Calls Use?

VoIP calls over data are surprisingly light:

• Voice call: approximately 40-80 MB per hour (less than 1.5 MB per minute)
• A typical 5-minute call: about 5-8 MB
• 10 calls per day averaging 3 minutes each: roughly 50-80 MB per day

Over a two-week trip with moderate call volume, HomeLink might use 500 MB to 1 GB of your data plan. That is a tiny fraction compared to the $100+ you would spend on roaming for the same calls.

Use Cases: Who Benefits Most

Business travelers. Clients and colleagues call your office or mobile number. HomeLink ensures you never miss a deal or deadline because you were overseas.

Parents traveling without kids. The school, the babysitter, the pediatrician — they all have your home number. Being reachable for emergencies is not optional.

Anyone expecting important calls. Waiting for a job callback, a mortgage approval, medical results, or legal communications? HomeLink keeps you in the loop.

Frequent travelers. If you travel regularly, setting up HomeLink becomes second nature. Activate before each trip, disable when you return.

HomeLink vs Other Solutions

HomeLink vs Google Voice: Google Voice is US-only and requires a US number. HomeLink works with numbers from 18+ countries.

HomeLink vs dual SIM with roaming: Roaming costs $1-3 per minute for calls. HomeLink uses eSIM data, which costs a fraction of that.

HomeLink vs WhatsApp calls: WhatsApp requires both parties to have the app. HomeLink works with regular phone calls — the caller does not need any app.

HomeLink vs local SIM with forwarding: A local SIM gives you a new number that nobody knows. HomeLink preserves your existing number.

Tips for the Best Experience

• Make sure your data plan has enough capacity. Budget an extra 1-2 GB for HomeLink calls over a two-week trip.
• Use WiFi for long calls when possible. If you are at your hotel, connect to WiFi and HomeLink calls will use WiFi instead of eSIM data.
• Set up forwarding before you leave. Test the setup while you are still at home to make sure everything works.
• Keep the TripoSIM app running. HomeLink needs the app in the background to ring your phone for incoming calls.
• Check call logs. The TripoSIM app logs all HomeLink calls so you can see missed calls and call duration.

Common Questions

Does the caller pay extra? No. The caller dials your regular home number and pays their normal rate. They have no idea the call is being forwarded internationally.

Can I make outgoing calls with my home number? HomeLink is primarily for receiving calls. For outgoing calls, use WhatsApp, FaceTime, or the TripoSIM VoIP feature.

What if I miss a HomeLink call? Missed calls go to your home carrier's voicemail, just like normal. You can check voicemail through your home carrier's visual voicemail or by dialing in.

Does HomeLink work on airplane mode? No. Your eSIM needs an active data connection. Once you land and enable your eSIM, HomeLink resumes working.

Can I use HomeLink with any eSIM plan? HomeLink works with any active TripoSIM data plan. It uses your existing data allowance for calls.

The Bottom Line

Your home phone number is your identity. Doctors, banks, schools, clients, and family all know that number. HomeLink lets you keep it active while traveling — no roaming fees, no missed calls, no complicated setups. Activate it before your next trip and stay reachable from anywhere in the world.
