# 📐 Kiwi VoIP – Choosing the Right SIM Card Size
When you order a mobile plan from **Kiwi VoIP**, you’ll receive a **3-in-1 physical SIM card**. This allows you to easily pop out the correct size to fit your device — no need to order a different SIM if you change phones!
#### 🧩 What is a 3-in-1 SIM?
A **3-in-1 SIM** includes all three common SIM card sizes, layered together in a single card. Simply pop out the size that fits your device.
| SIM Size | Dimensions | Common Devices |
| --- | --- | --- |
| **Standard SIM** | 25 x 15 mm, 0.76 mm thick | Older smartphones, mobile routers |
| **Micro SIM** | 15 x 12 mm, 0.76 mm thick | Mid-generation smartphones (e.g. iPhone 4–5c, Galaxy S3) |
| **Nano SIM** | 12.3 x 8.8 mm, 0.67 mm thick | Most modern smartphones (e.g. iPhone 5s+, Galaxy S6+) |
> 📘 **Tip:** If you’re unsure which SIM size to use, refer to your mobile phone’s user manual or do a quick model-specific search online.

#### 🔁 Can I Reuse the Same SIM for Another Phone?
Yes! As long as your phone supports one of the three sizes, you can reinsert or re-punch the SIM into the appropriate size. If you’ve damaged your SIM or need a new one, get in touch with us for a replacement.
