Before you fly: set am up for house

Di best advice na to do di setup for house, on Wi-Fi, few days before you comot. To install am need internet connection, and your sofa for house cool pass arrival hall to do am.

  1. 1Check your phone. Two boxes to tick: eSIM support and no carrier lock. "Add eSIM" for Settings na di sign for di first one. If dem buy your iPhone for mainland China, Hong Kong or Macao, check am well, becos plenti models from dia dey take two physical SIM and no eSIM.
  2. 2Buy your plan. Pick di destination or region, then di data and days. You no need account: guest checkout go only ask for your email.
  3. 3Find your QR code. E go land for your inbox sharp sharp afta payment, wit copy wey dem save inside your HelloSIM account and app.
  4. 4Install am. For iPhone: Settings → Mobile Data (or Cellular) → Add eSIM, then scan di code. For Android di route na usually Settings → Network & internet → SIMs, or Connections → SIM manager for Samsung, then Add eSIM; oda brands dey word am small different. If you no fit scan, type di SM-DP+ address and activation code from di email by hand.
  5. 5Give di line name. Give di new line clear name, like "Travel", so e go easy to see for Settings later.

To install early no dey waste anytin: di plan days no go start until di eSIM catch network for where you dey go.

Until di day wey you go travel, leave di new line off and keep your home line for mobile data, so di phone no go try connect on di travel line before you go.

When you land: how to connect

Once di plane don land and you fit off flight mode, follow dis steps:

  1. 1On di HelloSIM line for your SIM settings.
  2. 2Set am as di line for mobile data.
  3. 3On Data Roaming for di HelloSIM line. E no fit reach local networks without am, and since di data don already pay, roaming no go add anytin to di cost.
  4. 4Make sure say Data Roaming dey off for your home line, so your normal network roaming data no go enta di matter.
  5. 5Give di phone small time to find network. Once you see signal bars and 4G or 5G sign for di travel line, you don dey online.

Your home SIM fit stay on for calls and texts if you want make pipo still reach you on your usual number, but check wetin your home network dey charge for incoming calls abroad before you pick call.

How to make your data last pass

Some small habits go make internet eSIM last long well well:

  • Download offline maps for di cities wey you go visit before you comot from house.
