Here are some options and tips to consider for your AT&T phone plan:

### 1. **AT&T International Day Pass**
- **Cost**: $10 per day per line.
- **Coverage**: Covers over 210 destinations.
- **Details**: You can use your regular plan's data, calls, and texts as if you were in the U.S. It’s activated automatically when you use your phone abroad, and you only pay for the days you use it.
- **Best For**: Short trips where you need reliable service without much hassle.

### 2. **AT&T Passport**
- **Cost**: $70 for 30 days (2GB of data) or $140 for 30 days (6GB of data).
- **Coverage**: Available in over 200 countries.
- **Details**: Provides a set amount of data, unlimited texting, and discounted calling rates. Be mindful of your data usage, as overage fees can be high.
- **Best For**: Longer trips where you have a better idea of your data needs.

### 3. **Local SIM Card**
- **Cost**: Varies depending on the country and plan.
- **Details**: Purchase a local SIM card in your destination country for cheaper local rates. You’ll need an unlocked phone to use a local SIM.
- **Best For**: Extended stays or countries where you need a local number for better connectivity.

### 4. **eSIM**
- **Cost**: Varies by provider and data plan.
- **Details**: Many countries and global providers (like Airalo or GigSky) offer eSIMs, which you can download to your phone. eSIMs allow you to have both your AT&T number and a local number/data plan without switching physical SIM cards.
- **Best For**: Flexibility and convenience if your phone supports eSIM.

### 5. **Wi-Fi Calling**
- **Cost**: Free with a Wi-Fi connection.
- **Details**: Use Wi-Fi calling to make calls and send texts over a Wi-Fi network without incurring international roaming charges. This works just like a regular call/text but over the internet.
- **Best For**: Reducing costs when you have access to reliable Wi-Fi.

### 6. **Other Tips**
- **Check Coverage**: Before deciding, verify that your destination is covered under the AT&T plan you’re considering.
- **Unlock Your Phone**: If you plan to use a local SIM card, ensure your phone is unlocked by contacting AT&T before your trip.
- **Monitor Usage**: Be aware of your data usage to avoid unexpected charges, especially with limited data plans like AT&T Passport.

For short trips, the **International Day Pass** is typically the most convenient. For longer stays or frequent travel, consider a local SIM or an eSIM to save on costs.
